Store - 1
Total number of car = 15.
The number of
Black car = 7.
Grey car = 6.
White car = 2.
Store -2
The number of car wishes to buy = 3 car.
The number of black car sold = x .
The probability of 'x' = ?.
P ( x ) = P ( first black ) * P ( second black ) * P ( third is black )
P ( x ) = =
So the probability of number of car sold is black or P ( x ) =
Answer: 142°15'
Explanation:
Supplementary angles are angles that add up to make a straight angle ().
Therefore, we must find the angle ∠B such that
∠A + ∠B = 180° (1)
We know that ∠A = 37°45', so we can re-arrange equation (1) to find the magnitude of ∠B:
∠B = 180° - ∠A = 180° - 37°45' = 142°15'
So, the correct answer is
142°15'
