A normal resting heart rate for adults ranges from 60 to 100 beats per minute. If a heart beats fewer than 60 times a minute, that person has “bradycardia (brad-e-KAHR-dee-uh). It’s normal for a heart to beat faster during exercise, but if a heart beats over 100 beats per minute at rest, that person has “tachycardia” (ta·kuh·KAHR·dee·uh). Both bradycardia and tachycardia are abnormal heart rhythms, and a doctor should be consulted. Write a combined inequality that shows normal resting heart rate.

step-by-step explanation:

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
