Answer:
Step-by-step explanation:
First you need to break the shape up to rectangles to make it easier to solve.
bottom rectangle : 15 x 3 = 45m^2
Top rectangle : 12 x 3=36m^2
Middle rectangle : 12-3-3=6 (because we already solved the top and bottom part of it)
we need to work out the base so we do 15-5= 5cm
6 x 5 = 30m^2
add them all together
30+36+45=111m^2
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.
