Answer is a if I am not mistaken
We assume that male and female births are equally likely, it means that the probability of birth of male= probability of birth of female = 100%/2=50% or 0.5We have 2 independent events. So what will be the variants:
Male and FemaleMale and Male Female and Male Female and Female
All four variants are equally likely.Probability of each one is 1/4 = 0.25.So, Result "Female and Female"
are probability = 0.250 --- if round to three decimal places.
X+y/2=1
-2+6/2=1
-2 + 3 =1 true
⇒ ( -2, 6) is the solution
Everyday the number is tripled by 3 and x represents the number of days, which we don’t know, so it would be 3x.
He started with 24.
So the equation is:
24+(3x)
