In a carnival game you can either throw a target a which yields a $7 prize 12% of the time target b which yields a $3 prize 48% of the time. find the expected value of target b

The expected value of Target B is $ 1.44.

Step-by-step explanation:

Since,

Expected value = An outcome × its probability

Here, We have to find out the expected value of target B,

Given,

The probability of getting the price from target B = 48 % = 0.48,

Also, the value of getting the price from the target B = $ 3,

Hence, the expected value of Target B = 3 × 0.48 = $ 1.44
