Question

the probability of a fair coin Landing heads up in one tossis 1/2 if a coin is tossed 20 times how many times would the coin be expected to land heads up A.20B.1C.2D.10

Answer 1

Option D is correct.

The coin is expected to land heads up 10 times.

Step-by-step explanation

This is an expected value problem.

Expected value, the number of times an eventis expected to happen, is given as

E(X) = np

where

n = number of times the experiment is performed = 20

p = probability of our event happening (probability if the coin landing on the head) = ½

E(X) = Number of the coin expected to land on the head = ?

E(X) = np = (20) (½) = 10

Hope this Helps!!!
