For two events, M and N, P(M)=0.7, P(N|M)=0.3, and P(M'|N')

dexar [7]

Topic:Conditional Probability

For any two events A and B, where P(B) ≠ 0, P( A | B ) = P( A ∩ B ) / P( B ) = P( B | A) * P(A) / P(B)..i.e..{the probability of A given B is equal to the probability of A and B divided by the probability of B}

For a set of events A1, A2, A3, ... , An,
hence,
P(B)
= P(B and A1) + P(B and A2) + ... + P(B and An) 
= P(B | A1) * P(A1) + P(B | A2) * P(A2) + ... + P(B | An) * P(An)

P(M | N)
= P(N | M) * P(M) / P(N) 
= P(N | M) * P(M) / (P(N | M) * P(M) + P(N | M') * (1 - P(M)))
Substitute Values.... you get ?

3/4 = x/10 Please write the answer in decimal form. X = ?

Morgarella [4.7K]

Answer:

x=7.5

Step-by-step explanation:

To solve this, cross multiply

3/4=x/10

4*x=3*10

4x=30

Divide by 4 on both sides

x=7.5

Hope this helps! :)

The rabbit population in a certain area is 200% of last year's population. There are 900 rabbits this year. How many were ther

Nezavi [6.7K]

There would be 450 rabbits last year.

Since 900 is double 450, 200% of 450 is 900. (450 would be 100%, so you would double it).

Which one is bigger 30% or 4 /15 ???

Nikolay [14]

I believe 30% is bigger than $\frac{4}{15}$ .

To find the answer, you'd have to convert both the fraction and the percent into decimal form to see which one is truly bigger. Converting the percent is fairly easy. 30% would become 0.30 is decimal form. To find the fraction in decimal form, you'd have to divide the numerator by the denominator, which would be 4 ÷ 15, which makes : 2.6666666666666666666666667.

Now you compare easily. Which one is bigger? 2.666666666666666666666667 or 0.30?

0.30 is bigger. So 30% is bigger out of both of them.
