Question

A coin is tossed 100 times, a no. of times 6 came up. If the probability is 2/5. Find how many times 6 came up?​

Answer 1

Here, total number of trials = 100

Let x be the number of times occuring 6. 

We know, Probability of an ever = Frequency of the event occuring / Total number of trials 

⇒ x / 100 = 2 / 5 [∵ Probability is given]

⇒  x = 40

 

Hope Its help you
