Answer:
Step-by-step explanation:
Probability refers to chances of occurrence of any event.
Value of probability varies from to
Probability = Number of favorable outcomes ÷ Total number of outcomes
Total number of cards = 52
Number of spades = 13
Probability that the hand contains 5 spades =
Use
So,
Therefore,
Probability that the hand contains 5 spades =
Step-by-step explanation:
Given
f(x) = -5x - 1
and
g(x) = 2x + 2
Now
f(3) = - 5 * 3 - 1
= -15 -1
= -16
Also
g(-4) = 2 * (-4) + 2
= - 8 + 2
= - 6
9- find the ratio for boys to total student -> 5:12
x : 24 = 5 : 12
x = 10 boys
10- 800miles/60 minutes = 160miles/x minutes
x = 12 minutes
