To find the probability of spinning a 5 and rolling a 1, 2, or 3, we need to first find the probability of spinning a 5 and then find the probability of rolling a 1, 2, or 3.
1. Probability of spinning a 5:
Assuming the spinner has numbers 1 to 6, the probability of spinning a 5 is 1/6. This is because there is only one outcome out of six possible outcomes that results in spinning a 5.
2. Probability of rolling a 1, 2, or 3:
Assuming we are using a standard six-sided die, the probability of rolling a 1, 2, or 3 is 3/6 (or 1/2). This is because there are three favorable outcomes (rolling a 1, 2, or 3) out of six possible outcomes (rolling a number from 1 to 6).
To find the probability of both events happening, we multiply the individual probabilities:
Probability of spinning a 5 and rolling a 1, 2, or 3 = Probability of spinning a 5 × Probability of rolling a 1, 2, or 3
= 1/6 × 1/2
= 1/12
Therefore, the correct answer is not given in the options. The probability of spinning a 5 and rolling a 1, 2, or 3 is 1/12, but it is not listed among the given options.
how many numbers on the spinner? If n, then
