Multiplying mixed numbers and whole numbers 1 1/2 x 2/1 =

Nezavi [6.7K]

Answer: 3

Step-by-step explanation:

1. Convert the mixed number to fraction:

- Multiply the denominator of the fraction by the whole number.

- Add the product obtained and the numerator of the fraction.

- Write the sum obtained as the numerator and rewrite the original denominator of the fraction.

Then:

$1\ 1/2=\frac{(1)(2)+1}{2}=\frac{3}{2}$

2. Multiply the numerators.

3. Multiply the denominator.

4. Reduce the fraction.

Then:

$(\frac{3}{2})(\frac{2}{1})=\frac{6}{2}=3$

A and B are two events. Let P(A)=0.5 , P(B)=0.9 and P(A and B)=0.15 .

Nana76 [90]

Answer:

option-C

Step-by-step explanation:

we are given

Let P(A)=0.5

P(B)=0.9

P(A and B)=0.15

we know that

$P(A|B)=\frac{P(Aand B)}{P(B)}$

now, we can plug values

$P(A|B)=\frac{0.15}{0.9}$

$P(A|B)=0.16666$

but we have

P(A)=0.5

we can see that both are not equal

$P(A|B)\neq P(A)$

so, A and B are not independent

so, option-C........Answer
