Answer:
The expected number of coupon is [tex]E(X) = 1.6[/tex]
Step-by-step explanation:
From the question we are told that
The probability that a $10 coupons delivered by mail will be redeemed is p = 0.16
The sample size is n = 10
Generally the expected number of coupons that will be redeemed is mathematically represented as
[tex]E(X) = np[/tex]
=> [tex]E(X) = 10 * 0.16[/tex]
=> [tex]E(X) = 1.6[/tex]
