Question

It was determined that the probability that 2 or fewer students withdraw from the course will be the sum of these events.

Using the table, we found f(0) = 0.0536, f(1) = 0.1704, and f(2) = 0.2556. Find this probability to four decimal places.

probability of 2 or fewer students withdraw	=	f(0) + f(1) + f(2)
	=	0.0536 + + 0.2556
	=

Answer 1

Answer #1

n = 18

p = 0.10 0.15 0.20 0.25

When p = 0.15, f(0) = 0.0536, f(1) = 0.1704, and f(2) = 0.2556.

Probability that 2 or fewer students withdraw from the course

= f(0) + f(1) + f(2)

= 0.0536 + 0.1704 + 0.2556

= 0.4796
