Answer:

The probability of the next two customers both select key lime pie is 1/15

Step-by-step explanation:

No. of slices of cakes = 3

No. of key lime pies = 3

No. of ice cream sundaes = 4

Total deserts = 3+3+4=10

We are supposed to find The probability of the next two customers both select key lime pie

Probability of selecting key lime pie by first customer =\frac{3}{10}

So,Total deserts =10-1=9

No. of key lime pies = 3-1=2

So,Probability of selecting key lime pie by second customer = \frac{2}{9}

So,the probability of the next two customers both select key lime pie=\frac{3}{10} \times \frac{2}{9} =\frac{1}{15}

Hence the probability of the next two customers both select key lime pie is 1/15
