What is the probability of landing on an even number and then landing on an 8?

Write your answer as a percentage.

Answer 3

The possible outcomes when picking two cards are: (2,2), (2,3), (2,4), (3,2), (3,3), (3,4), (4,2), (4,3), (4,4).

Out of these, only (3,3) is the outcome where both numbers are odd.

Therefore, the probability of picking an odd number and then picking an odd number is 1 out of 9 or 1/9.

Answer 4

Apologies for the mistake. Let's calculate again.

Out of the possible outcomes when picking two cards (2,2), (2,3), (2,4), (3,2), (3,3), (3,4), (4,2), (4,3), (4,4), there is only one combination where both numbers are odd - (3, 3).

Therefore, the probability of picking an odd number and then picking an odd number is 1 out of 9 or 1/9.

Answer 5

There is only one even number on the spinner, which is 8.

When spinning the spinner twice, there are 4 possible outcomes for each spin. So, there are a total of 4x4 = 16 possible outcomes when spinning the spinner twice.

The only outcome that satisfies the condition of landing on an even number and then landing on an 8 is (8,8).

Therefore, the probability of landing on an even number and then landing on an 8 is 1/16.

To convert this probability into a percentage, we multiply by 100:

1/16 * 100 = 6.25%.

So, the probability of landing on an even number and then landing on an 8 is 6.25%.
