Answer: The expected value of purchasing a raffle ticket would be $0.3449.
Step-by-step explanation:
Since we have given that
Number of tickets = 5500
Number of flower arrangements = 20
Number of gift certificates = 20
So, Probability that wining $70 at flower arrangement =
Probability that wining $25 at gift certificates =
So, Expected value of purchasing a raffle ticket would be
Hence, the expected value of purchasing a raffle ticket would be $0.3449.

Answer:
'b' and 'c' = 119 degrees
Step-by-step explanation:
Given that this is a basic intersection of straight lines, we can assume 'b' and 'c' are equal as well as the given angle and it's opposite. Given 61 degrees and and two straight lines we can just take 180 degrees - 61 degrees and we get 119 degrees, I solved for 'b', but this will give the same answer for 'c', as 'b' and 'c' are equal.
Answer:
Step-by-step explanation:
first of all arrange this data from ascending to descending order.
11,15,15,15,16,17,18,19,20,22,23
use formula
N+1/4 (N means no of observations)
11+1/4
12/4
3 rd term
therefore Q1=15
