Answer:
16.75 Dollars for each Ticket
Step-by-step explanation:
They are three friends so the total money they spent is 75 Dollars so a popcorn costs 8.25 EACH friend so
8.25 x 3
= 24.75
24.75 dollars was spent on the 3 popcorns.
Subtract the total money spent and the total money spent on the 3 popcorns so
75. 00 - 24.75
= 50.25
50.25 dollars were totally spent on the tickets but we're looking for each ticket so divide it by 3.
50.25/3
= 16.75
16.75 dollars each were spent on each ticket.
Thank you and pls mark me as brainliest! Love y'all!
For the fifth term, n = 5.
Just replace n with 5 in the expression.
Then evaluate the expression.

Answer:
a) the probability of winning A and B is 0.4 (40%)
b) the probability of not winning either project is 0.1 (10%)
Step-by-step explanation:
if 2 events are independent then
P(A∩B)=P(A)*P(B)
where
P(A)= probability of winning project A
P(B)= probability of winning project B
P(A∩B)= probability of winning projects A and B
replacing values
P(A∩B)=P(A)*P(B) = 0.50 * 0.8 = 0.4
b) since
P(A∪B) = P(A) + P(B) - P(A∩B) = 0.50 + 0.8 - 0.4 = 0.9
where
P(A∪B) = probability of winning A or B
therefore
probability of not winning either project = 1 - P(A∪B) = 1 - 0.9 = 0.1 (10%)
