can you help me
Hawa owns a small business selling clothing. She knows that in the last week 5 customers paid cash, 30 customers used a debit card, and 96 customers used a credit card.
Based on these results, express the probability that the next customer will pay with a debit card or a credit card as a percent to the nearest whole number.

There is a spinner with 8 equal areas, numbered 1 through 8. If the spinner is spun one time, what is the probability that the result is a multiple of 2 and a multiple of 3?

what about
There is a spinner with 15 equal areas, numbered 1 through 15. If the spinner is spun one time, what is the probability that the result is a multiple of 4 and a multiple of 3?

Yes, I can help you with that!
To find the probability that the next customer will pay with either a debit card or a credit card, we need to add up the number of customers who paid with these methods and divide by the total number of customers:
P(debit or credit) = (30 + 96) / (5 + 30 + 96) = 126 / 131
To express this probability as a percentage to the nearest whole number, we need to multiply by 100 and round to the nearest whole number:
P(debit or credit) \* 100 = 126 / 131 \* 100 ≈ 96%
Therefore, the probability that the next customer will pay with a debit card or a credit card is about 96%.

To determine the probability that the result is a multiple of 2 and 3, we need to first find the numbers that are multiples of 2 and 3.
Multiples of 2: 2, 4, 6, 8
Multiples of 3: 3, 6
The only number that is a multiple of both 2 and 3 is 6. Therefore, there is only one outcome that satisfies both conditions.
Since there are a total of 8 possible outcomes, the probability of spinning a multiple of 2 and 3 on the spinner is:
P(multiple of 2 and 3) = 1/8
Thus, the probability that the spinner will show a result that is both a multiple of 2 and a multiple of 3 is 1/8.

To determine the probability that the result is a multiple of 4 and 3, we need to first find the numbers that are multiples of 4 and 3.
Multiples of 4: 4, 8, 12
Multiples of 3: 3, 6, 9, 12, 15
The only number that is a multiple of both 4 and 3 is 12. Therefore, there is only one outcome that satisfies both conditions.
Since there are a total of 15 possible outcomes, the probability of spinning a multiple of 4 and 3 on the spinner is:
P(multiple of 4 and 3) = 1/15
Thus, the probability that the spinner will show a result that is both a multiple of 4 and a multiple of 3 is 1/15.
