Answer:
a. 0.25
b. 0.50
c. 0.75
Step-by-step explanation:
P(E1) = 0.25
P(E2) = 0.25
P(Es) = 0.25
P(E) = 0.25
a. Since there are 4 outcomes with the same probability of occurring, the probability of E occurring is:

b. The probability of any two outcomes occurring is twice the probability of a single outcome occurring

c. The probability of any three outcomes occurring can be written as 100% minus the probability of the remaining outcome occurring

16/80 = 1/5 = 0.2
Therefore, 0.2 x 100% = 20%.
Answer:table 1 would be y=x-3 and table 2 is y=x-5
Step-by-step explanation:
6 + 7b - 7 = 5 + b
7b - 1 = 5 + b
7b = 5 + b + 1
7b = b + 6
7b - b = 6
6b = 6
b = 1
Answer: B)
