Answer:
P = 57/1105
P = 0.052
Step-by-step explanation:
Given:
Total number of dummy tickets = 20
Total number of tickets with value = 10 + 10 + 12 = 32
Total number of tickets in the box = 20 + 32 = 52
The probability of picking 3 tickets randomly from the box without replacement and the three are dummy (with no value) is;
P = 20/52 × 19/51 × 18/50
(As each one is picked it reduces the total number of tickets and also the number of dummy tickets by one)
P = 57/1105
P = 0.052
Answer:
1/31 = 0.0323 probability that Charity gets just chocolate chips and a cherry.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Number of subsets in a set of n elements:
The number of subsets in a set of n elements, including the empty set, is given by:
Up to five toppings:
Up to five toppings means that the total number of possibilities is:
We subtract one to disconsider the option with no toppings.
What is the probability that Charity gets just chocolate chips and a cherry?
Chocolate chips and cherry is 1 subset, so
The probability is:
1/31 = 0.0323 probability that Charity gets just chocolate chips and a cherry.
