1. B: On a six-sided die, the probability of throwing any number is 1 in 6. The probability of throwing a 3 or a 4 is double that, or 2 in 6. This can be simplified by dividing both 2 and 6 by 2. Therefore, the probability of throwing either a 3 or 4 is 1 in 3. 2.
What is the probability of drawing a red ball on a single draw? Solution: Probability of drawing a red ball and replacing it = 3/10. Total probability = (3/10) =0.3 or 30%. Question 11: In a class of 60 students, 30 are boys. If one student is randomly selected, what is the probability of selecting a girl? Solution: Total girls = 60 - 30 = 30.

Determine the probability of 3 of 5 born children being sons if the probability of a children to be a boy equals P(A) = 0,51. Solution: Binomial probability expression.
Problem 1 : Two balls are drawn from a bag containing 5 white and 7 black balls at random. What is the probability that they would be of different colors ? Solution : Total number of balls = 5 white + 7 black. n(s) = 12 balls. Let A be the event of selecting white ball and B be the event of selecting black ball. n(A) = 5 and n(B) = 7
Actively solving practice problems is essential for learning probability. Strategic practice problems are organized by concept, to test and reinforce understanding of that concept.Homework problems usually do not say which concepts are involved, and often require combining several concepts.Each of the Strategic Practice documents here contains a set of strategic practice problems, solutions to ...
What is the probability of each sample point? Solution: The sum of probabilities of all the sample points must equal 1. And the probability of getting a head is equal to the probability of getting a tail. Therefore, the probability of each sample point (heads or tails) must be equal to 1/2.

Probability and Probability Distributions Problems Q.1. Among male birds of a species, 20% have a particular gene. Among females of the species, 10% have the gene. The males comprise 40% of all the birds of the species (thus, females comprise 60%). p.1.a. What is the probability a randomly selected bird of this species has the gene? p.1.b.
2. The probability of the event of getting an even number. 3. The probability of the event of getting an odd number. 4. The probability of the event of getting a four or five. 5. The probability of the event of getting a number less than 5. Solution:
Examples of Probability Problems with Solutions in Real Life. Probability problems refer to mathematical scenarios or situations where the outcome is uncertain, and the goal is to determine the likelihood of different outcomes occurring. These problems often involve calculating probabilities, which represent the chance or likelihood of an event happening.
If the probability of drawing a white ball is half of the probability of drawing a red ball then find the number of white balls in the bag. Solution: Let the number of white balls be n. The number of red balls = 8. Therefore, the possible number of outcomes = n + 8. Now, the probability of drawing a white ball = \(\frac{n}{n + 8}\).
