if 2 cm 21 km
9cm ? km
?×2=9×21
?=189÷2
?=94,5 km
The answer is A.5/8.
Why?
Multiply 1/4 with 2/2 to get the same denominator as 7/8, 8. That will yield 2/8.Then, simply subtract 2/8 from 7/8 (7/8 - 2/8), and that equals 5/8.
Hope this helps!
Answer:
The probability that at least one is a boy is 0.525
Step-by-step explanation:
P(Baby being a girl) = 0.475
Now, if A is any arbitrary event . Then:
as we know P(A)+ P(not A) = 1
⇒ P(A not happening) = 1 - P(A event happening)
Also, P( baby not being a girl) = P(baby being a boy)
So, P(baby being a boy) = 1 - P( baby being a girl)
= 1 - 0.475 = 0.525
Hence, the probability that at least one is a boy is 0.525
The answer would be 60 because its multiplication all those numbers
