Question

a die was rolled 100 times and the number of time 6 came up was noted. If the experimental probability calculated from this information is 2/5, then how many times 6 came up? Justify your answer.

Answer 1

total no. of times the rolled=100
probability of 6 came up=2/5
No. of times 6 come=x
probability=x/100
2/5=x/100
x=2×100/5
x=200/5
x=40
so 6 comes 40 times
hope it is correct and will help you

Answer 2

Answer:

40

Step-by-step explanation:

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
