Shea has a bag of blocks. Without looking in the bag, she selects a block, records its color, and puts it back in the
bag. All blocks are equally likely to be chosen. She
performs 100 trials.
Number of times a red block was chosen
62
Number of times a yellow block was chosen 21
Number of times a blue block was chosen 12
Number of times a pink block was chosen
ол
Based on the data Shea collected, what is the estimated probability, in
simplest form, of choosing a red block from the bag?
A.
31
50
B.
50
31
c. 31
100

idk

step-by-step explanation:

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate

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

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
