Answer:
a.
Step-by-step explanation:
Probability that is a AB type blood given is a Male
P(AB/M) = 42/500 = 21/250
Probability that they are Male with an AB type blood out of all AB type blood people = Probability that is a Male out of all students
P(M∩AB) = P(M)
(42/105) = (500/1,250)
.4 = .4 ✅
The events "the student is male" and "the student has blood type AB" are independent events.
The answer is C something like a step - by - step explanation
Answer:9.5
Step-by-step explanation:74 divided by 8 is 9.5
We have, 75% × x = 189
or,
75/100 × x = 189
Multiplying both sides by 100 and dividing both sides by 75,
we have x = 189 × 100/75
x = 252
Proof: 25% of 252 = 63.
252 - 63 = 189
No idea what the anwser is to that question. maybe look it up on safari or here
