Carvel sold 87 scoops of ice cream in one hour. 65 of them were vanilla ice cream. What is the probability that the next scoop that they sell will be vanilla?

74.71%

Step-by-step explanation:

To calculate the experimental probability of the next scoop that they sell being vanilla, we need to divide the amount of scoops of ice cream that were vanilla (65 scoops) by the total amount of scoops of ice cream sold (87 scoops):

Probability of next scoop being vanilla = 65 / 87 = 0.7471  = 74.71%

The experimental probability of the next scoop they sell being vanilla is 74.71%.

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.

25/6

step-by-step explanation:

you multiply 4 by the denominator (4*6=24) and add it to the numerator which makes it 25/6.
