Question

A football quarterback has 2 more chances to throw a touchdown before his team is forced to punt the ball. He misses the receiver on the first throw 30% of the time. When his first throw is incomplete, he misses the receiver on the second throw 10% of the time. What is the probability of not throwing the ball to a receiver on either throw?

@deepika.comet thanks again

Answer 15

@Frostbite do you understand it?

Answer 16

@TavTav Yeah I understand it, but lets see if I can make you understand:

But first we got to talk about two concepts: dependent and independent events. Something you are familiar with?

Answer 17

yess

Answer 18

Okay, these events, are they dependent or independent?

Answer 19

independent

Answer 20

I would say the same, in that case we may use the rule of multiplication of independent probabilities:

When two events, A and B, are independent, the probability of both occurring is
\[\Large P(A|B)=P(A) \times P(B)\]

Answer 21

so multiply .3*.1 ??? and that will be my answer

Answer 22

I would think so yes, if they are indeed independent events. a little unsure

Answer 23

thank you , can you help me with another one?

Answer 24

Yea sure. Gotta be going soon though.

Answer 25

Josh believes the Spanish club students at his school have an unfair advantage in being assigned to the Spanish class they request. He asked 500 students at his school the following questions: "Are you in the Spanish club?" and "Did you get the Spanish class you requested?" The results are shown in the table below:


Spanish Club Not in Spanish Club Total
Received Spanish class requested 265 100 365
Did not get Spanish class requested 70 65 135
Total 335 165 500


Help Josh determine if all students at his school have an equal opportunity to get the Spanish class they requested. Show your work and explain your process for determining the fairness of the class assignment process.
