Step-by-step explanation:
To find the expected value, E(X), or mean μ of a discrete random variable X, simply multiply each value of the random variable by its probability and add the products. The formula is given as .
Here, x represents values of the random variable X, represents the corresponding probability, and symbol
represents the sum of all products
. Here we use the symbol
for the mean because it is a parameter. It represents the mean of a population.
In this case, the expected value of the ticket is
This means that Ahmad can expect to win 20.97 AED for the ticket.
