The expected value of purchasing a raffle ticket is -0.647.

What is the Expected Value of a Probability & Statistical Analysis?

The expected value is derived in probability analysis by the multiplication of each of the potential possibilities by the likelihood that each result will occur and then adding all of those values together.

Using the formula below, we can calculate the expected value as follows:

$\mathbf{ E(X)= \sum^(n)_(i=1)X_i P(X_i)}$

However, the probability (Pr) of each event can be categorized as follows:

Pr (to win a flower arrangement ) $\mathbf{=(20)/(5500)}$

Pr (to gift a certificate) $\mathbf{=(20)/(5500)}$

Pr (no win) ) $\mathbf{=(5500 - 20 - 20)/(5500)=(5460)/(5500)}$

Thus;

$\mathbf{E(X) = 70((20)/(5500) * 25 (((20)/(5500) )- 1((5460)/(5500) )}$

$\mathbf{E(X) =-0.647}$

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 = $(20)/(5500)=(1)/(275)$

Probability that wining $25 at gift certificates = $(20)/(5500)=(1)/(275)$

So, Expected value of purchasing a raffle ticket would be

$70* (1)/(275)+25* (1)/(275)\n\n=0.254+0.0909\n=\$0.3449$

Hence, the expected value of purchasing a raffle ticket would be $0.3449.
