A football quarterback enjoys practicing his long passes over 40 yards. He misses the first pass 40% of the time. When he misses

on the first pass, he misses the second pass 20% of the time. What is the probability of missing two passes in a row?

Answer:

8% or 0.08

Step-by-step explanation:

Probability of missing the first pass = 40% = 0.40

Probability of missing the second pass = 20% = 0.20

We have to find the probability that he misses both the passes. Since the two passes are independent of each other, the probability that he misses two passes will be:

Probability of missing 1st pass x Probability of missing 2nd pass

i.e.

Probability of missing two passes in a row = 0.40 x 0.20 = 0.08 = 8%

Thus, there is 8% probability that he misses two passes in a row.

Answer: 0.08

Step-by-step explanation:

Let A be the event that football quarterback misses the first pass, and B be the event that football quarterback  misses the second pass.

Then , the probability that he misses the first pass P(A)= 0.40

The  probability that he misses the second pass P(B|A)=0.20

The formula of conditional probability :-

P(B|A)=\dfrac{P(B\cap A)}{P(A)}\\\\\Rightarrow\ P(B\cap A)=P(B|A)\cdot P(A)

\Rightarrow\ P(B\cap A)=0.20\times0.40=0.08

Hence, the probability of missing two passes in a row =0.08

Describe the effect an increase in i, the interest rate applied to the present value, has on the monthly payment P in the formul
VARVARA [1.3K]

Answer:

B. An increase in i, the interest rate, will create an increase in P, the monthly payment.

Step-by-step explanation:

We have the formula for the monthly payment as,

P=\frac{i \times PV}{1-(1+i)^{-n} },

where P = monthly payment, i = rate of interest, PV = present value and n = time period.

Now, as i increase we get that (1+i) increases and so (1+i)^{n} increases.

This gives us that, \frac{1}{(1+i)^{n} } decreases and so 1-\frac{1}{(1+i)^{n}} decreases

Therefore, \frac{1}{1-(1+i)^{-n} } increases.

So, we get that as i increases , the value of P will increase.

Hence, option B is correct.
