Question

Find P(blue and odd).

Answer 1

P(blue and odd) =
`(1)/(10)`

There are 10 possible outcomes

There are 2 possible blue outcomes, hence

P(blue) =
`(2)/(10)` =
`(1)/(5)`

There are a possible of 5 odd numbers, hence

P(odd) =
`(5)/(10)` =
`(1)/(2)`

P(blue and odd) =
`(1)/(5)` ×
`(1)/(2)` =
`(1)/(10)`

Answer 2

The probability of blue and odd number is 1/10

Explanation:

We are given some number with color box.

Sample Space:

1B, 2B, 3G, 4G, 5G, 6Y, 7P, 8P, 9P, 10P

Total sample space is 10.

We need to find the probability of blue and odd number.

Let A be event getting blue and B be event getting odd number.

`P(A)=(2)/(10)`

`P(B)=(5)/(10)`

`P(A\cap B)=(1)/(10)`

The probability of blue and odd number.

`\text{P( Blue and Odd)} = P(A\cap B)`

`\text{P( Blue and Odd)} = (1)/(10)`

Hence, The probability of blue and odd number is 1/10
