Question

A coin is tossed 200 times, if the probability of getting a head is 5/8, how many times tail is obtained in all in tossing the coin?

​

Answer 1

You would get tails 75 times, or 75:200

Explanation:

5:8 = x:200

multiply 8 by 25 to get 200

multiply 5 by 25 to get x (125)

Probability to get heads is 125 so subtract 200 by 125

200 - 125 = 75
