Question

a die was rolled 150 times and the number of times 4 came up ,was noted . if the experimental probability calculated from this in formation is 2/5 ,then how many times 4 came up?justify your answer

Answer 1

Heya mate,

Here is your answer,. ⬇️⬇️

${ANSWER :-}$
___________

$<i>$ Let the number of times four came up be x.

Here, 4 is the desired outcome.

And the die was rolled 150 times.

Thus, 150 is the total number of outcomes.

Therefore, we have,

Probability = number of desired outcomes / the total number of outcomes.

Thus, 2/5 = x / 150
Or, x = 2/5 * 150 = 60.

➡️ Hence, 4 came up 60 times.
