Answer:
0.0975 or 9.75%
Step-by-step explanation:
Assuming that no engines fail simultaneously, the probability that exactly one engine fails is the probability that the first engine fails (15%) multiplied by the probability that the second engine does not fail (100% - 35%):

The probability of exactly one engine failure is 0.0975 or 9.75%
Answer:
Let's try and figure it out yearly:
So for the first year the deposits would amount to 40 * 12 = $480
Now since the interest rate is applied yearly we will assume that the interest rate will be applicable to the amount that is left after the first year of deposits
So that would be 889.98 - 480 = 409.98
409.98 * 14.99 % = 61.45
The new amount owed for the second year would be 409.98 + 61.45 = 471.43
So by the end of the second year the debt would of been wiped clean with $8.57 to spare.
So the answer would be 24 months

Probability that first student prefers mechanical pen = 0.30
P(first student does not and second student does) = 0.70 * 0.3 = 0.21)
P( selecting 2 or fweer) = 0.30+ 0.21) = 0.51 or 51%
3.73494 x 10^9
