She wants to use 3/4 of the recipe and 3/4 of a cup 4 times equals three cups. Three cups is 3/4 of 4 cups.
There is 1/5000 chance to win first place of $2000,
1/5000 chance to win second place of $500
3/5000 chance to win third place of $100
10/5000 chance to win the consolation prize of $25.
The ticket costs $1.
We multiply each probability by the amount, and subtract the ticket cost, to get the expected net earnings:
(1/5000)($2000) + (1/5000)($500) + (3/5000)($100) + (10/5000)($25) - $1 = $(-0.39).
This means that there is an expected loss of $0.39.
Answer:
TbH my brain is to tired lol
Step-by-step explanation:
sorry
Step-by-step explanation:
a)
well, logically, it must be M, 2
b)
this is a combined probability for one single pair of possible outcomes.
there are 15 pairs, all with the same probability.
so, P(Q, 4) = number of desired outcomes / number of possible outcomes = 1/15
as combined probability we can also say the probability to get 4 on one wheel is 1/5, and the probabilty to get Q on the other wheel is 1/3
so, P(Q, 4) = 1/3 × 1/5 = 1/15
Answer: 0.17%
Step-by-step explanation:
0.166% × 100 =
(0.166 ÷ 100) × 100 =
(0.166 × 100) ÷ 100 =
16.6 ÷ 100 =
0.166 ≈
0.17
