Answer:
2/15.
Step-by-step explanation:
The prime numbers in the first 10 numbers are: 2, 3, 5, 7 . That is a total of 4.
Prob( first number drawn is prime) = 4/10 = 2/5.
Prob( second number drawn is prime) = 3/9 = 1/3.
Required probability is 2/5 * 1/3
= 2/15.
Say width equals x.
Length = 3x - 4
Solve for x: 72 = 2(3x - 4) + 2x
72=6x-8+2x
80=8x
X=10
So width = 10
Length= 3(10) - 4 = 26
