Answer:
75
Step-by-step explanation:
you have 600 = 8 and you want to break it down into just 1 hour so you divide both sides by 8
600/8 = 75
<span>"Solving for variable 'b'.
Move all terms containing b to the left, all other terms to the right.
Add '-2b' to each side of the equation.
4 + b + -2b = -5 + 2b + -2b
Combine like terms: b + -2b = -1b
4 + -1b = -5 + 2b + -2b
Combine like terms: 2b + -2b = 0
4 + -1b = -5 + 0
4 + -1b = -5
Add '-4' to each side of the equation.
4 + -4 + -1b = -5 + -4
Combine like terms: 4 + -4 = 0
0 + -1b = -5 + -4
-1b = -5 + -4
Combine like terms: -5 + -4 = -9
-1b = -9
Divide each side by '-1'.
b = 9
Simplifying
b = 9"- geteasysolution.com</span>
5 Girls + 3 Boys =8 (sample size)
Probability of choosing 1 boy P(1 B) = 3/8
Probability of NOT CHOOSING ANY BOY = 1-3/8 =5/8
Now apply the binomial probability to choose 3 Boys:
8C3(3/8)³(5/8)⁵ ==>P(All boys) = 0.28
