The probability of randomly choosing 1 blue sock is 7/10. The probability of randomly choosing 2 blue socks in a row is 7/10 x 7/10 = 49/100.
The probability is 10/50 = 1/5.
To find the experimental probability of choosing a green marble, first calculate the total number of marbles: 7 red + 9 yellow + 14 green + 10 purple = 40 marbles. The probability of choosing a green marble is the number of green marbles divided by the total number of marbles, which is 14 green / 40 total = 0.35. Thus, the experimental probability of choosing a green marble is 0.35, or 35%.
If the selection is random, the probability is 16/52 = 4/13.
The probability for a single random choice, is 6/13.
It is 10/13.
If 10 out of 26 are girls, then the probability of randomly choosing a boy is 16 out of 26, or 8 out of 13, or about 0.6154.
If the choice is unbiased, the change is 14/(10+14). If the chooser prefers choosing boys, the probability is 0.
2/5
It is 2/52 or 1/26.
The probability of choosing a 10 is 4/52; likewise a Jack is 4/52. The probability of 10 or Jack is 4/52 + 4/52 = 8/52 or 2/13.
The probability of an event, such as selecting a multiple of two from a set of numbers, depends on the size of the set and how many of those numbers are multiples of two. For example, in the set of integers from 1 to 10, there are five multiples of two (2, 4, 6, 8, 10). Thus, the probability P(multiple of two) in this case would be 5 out of 10, or 0.5. To determine the probability in a different context, simply apply the same principle by counting the multiples of two in the given set and dividing by the total number of elements in that set.
