Answer:
The required probability is 0.09875
Step-by-step explanation:
From the given information;
the probability of repairing the telephones = 0.70
the probability of the replaced = 0.30
Suppose we consider Mto denotes the telephone that is submitted for service while under warranty and must be replaced.
Then;
p = P(S) = P(replaced | submitted) P(submitted)
= 0.30 × 0.20
= 0.06
Now, the probability that exactly two will end up being replaced under warranty given that it assumes a binomial distribution where n = 10 and p = 0.06



Answer:
C
Step-by-step explanation:
If you find how many units there are for each point you will be able to figure out the reflection
Step-by-step explanation:
the given shape is a parallelogram so, adjacent angles are supplementary.
so,
=》3y - 15° + 2y = 180°
=》5y = 180° + 15°
=》y = 195° ÷ 5
=》y = 39°
now , Angle A = Angle C
( they are opposite angles of a parallelogram )
=》Angle A
=》 2 × y
=》2 × 39°
=》78°
hence, Angle A = 78°
