Step 1
Answer:- Given, A building contractor buys 70% of his cement from supplier A and 30% from supplier B.
That is , P( supplier A) = 70% = 0.70
P( supplier B) = 30% = 0.30
Aslo given , A total of 75% of the bags from A arrive undamaged, while 80% of the bags from B arrive undamaged.
That is, P(undamaged from A) = 75% = 0.75
P(undamaged from B) = 80% = 0.80
