To find the probability of selecting a multiple of 2 or 3 from the numbers 1 to 10, first identify the multiples: the multiples of 2 are 2, 4, 6, 8, and 10; the multiples of 3 are 3, 6, and 9. The number 6 is counted in both categories, so the unique multiples of 2 or 3 are 2, 3, 4, 6, 8, 9, and 10, totaling 7 unique numbers. Since there are 10 possible selections, the probability is 7/10 or 0.7.
To find the probability of not selecting a multiple of 2 or a multiple of 3 from the numbers 1 to 10, we first identify the multiples: the multiples of 2 are 2, 4, 6, 8, 10, and the multiples of 3 are 3, 6, 9. The multiples of either 2 or 3 are 2, 3, 4, 6, 8, 9, and 10, totaling 7 numbers. This leaves us with 1, 5, and 7 as the numbers that are neither, giving us 3 favorable outcomes. Therefore, the probability is 3 out of 10, or 0.3.
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.
