Question

a coin is tossed 400 times and the probability of getting 2 head is 90 times find out the percentage
​

Answer 1

Answer:

Given,

Total number of events = 400

(a) No. of times two heads occur = 112

Probability of getting two heads = 112/400 = 7/25

(b) No. of times one heads occur = 160

Probability of getting one heads = 160/400 = 2/5

(c) No. of times no heads occur = 128

Probability of getting no heads = 128/400 = 8/25

that is equal to 32%
