Look up what is mean and calculate it.
Answer:
A) Pd = 13/28
B) Pd = 7/16
Step-by-step explanation:
Given;
Drama = 2
Comedy = 1
Science fiction = 5
Total = 8
a) The probability of selectingat least one drama movie Pd;
Pd = 1 - Pd'
Without replacement;
Probability of not selecting a drama movie Pd' is;
Pd' = 6/8 × 5/7 = 15/28
Pd = 1 - 15/28
Pd = 13/28
b) with replacement;
Probability of not selecting a drama movie Pd' is;
Pd' = 6/8 × 6/8 = 9/16
Pd = 1 - 9/16
Pd = 7/16
If its 20 more than last month that means x + $20 = $70, solve that and you get x = $50, last month she saved $50
