The spinner below is divided into 16 equally spaced sections. if the spinner is spun 20 times, what is the probability of getting a perfect square exactly seven times? (30 points since i need it now)

11.24%

Step-by-step explanation:

1,4,9,16 are the only perfect square numbers in the 16 number wheel so it would be . 20C7*1/4^7*3/4^13

-20 is the numbers of times spun

-7 is the number we are looking for

-1/4 is 4/16 which is the number of perfect squares

-3/4 is 12/16 which is the numbers of non perfect squares

-^7 is the number we are looking for

-^13 is 20-7
