Answer:
The probability of selecting 5 both times is 0.002.
Step-by-step explanation:
We are given that you randomly select an integer from 0 to 19 (inclusively) and then randomly select an integer from 0 to 24 (inclusively).
And we have to find the probability of selecting 5 both times.
As we know that the probability of an event is given by;
Probability =
Now, here between integer from 0 to 19 (inclusively);
Number of times 5 comes = 1
Total number of integers = 20
Similarly, between integer from 0 to 24 (inclusively);
Number of times 5 comes = 1
Total number of integers = 25
So, the required probability =
= = 0.002
Hence, the probability of selecting 5 both times is 0.002.
