The tigers, a football team, must gain 10 yards in the next four plays to keep possession of the ball . the tigers lose 18 yards, gain 5 yards , and lose 4 yards . how many yards do they need to keep possession

they need 23 yards to keep possession of the ball

Step-by-step explanation:

they must gain 10 yards to keep the ball.

Word form

First you do 10 times 4 equals 40

Second you do 40 minus 18 equals 22

Third you do 22 plus 5 equals 27

Last you do 27 minus 4 equals 23

They would need 23 yards to keep possession of the ball.

Math form

10*4=40

40-18=22

22+5=27

27-4=23

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
