How many ways can a teacher pick a group of 3 students from his class of 32?
A) 96 ways B) 29,760 ways C) 4,960 ways D) 35,960

( ASAP Please :) )

the answer is B) 29,760

Step-by-step explanation:

you multiply the original by on less than itself and then repeat for how many people in the group for example

32 times 31 is 992 then you multiply by 30 which is 29,760

85.560%

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
