Explanation:

Answer 2

The expected value of x in the data given is 33/49.

The expected value is defined as ;

• ∑x*p(x)

From the table given;

∑x*p(x) = [0 × (16/49)] + [1 × 24/49] + [2 × 9/49]

∑x*p(x) = 0 + 24/49 + 18/98

∑x*p(x) = 24/49 + 18/98

The L.C.M of the denominator (49 and 98 = 98)

24/49 + 18/98 = (48 + 18) / 98

24/49 + 18/98 = 66/98 = 33/49

Hence, ∑x*p(x) = 33/49
