Here is your answer,. ⬇️⬇️
___________
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.
