Answer:
20% probability that the next customer will pay with cash
Step-by-step explanation:
A probability, as a decimal, is the number of desired outcomes divided by the number of total outcomes.
To find as percent, we multiply by 100.
In this question:
Total of 54+63+153 = 270 customers.
Of those, 54 paid with cash.
Based on the number of customers from last week, what is the probability as a percent that the next customer will pay with cash?
54/270 = 0.2
0.2*100 = 20%
20% probability that the next customer will pay with cash
P(A)=0.2
P(B)=0.3
P(A and B)= 0.2 x 0.3=0.06
No they do not. Find the common denominator then add them together. Dived the numerator my the denominator and you should get your answer. Sorry I am to lazy to do fractions right now. Lol
