Question

(this is probability) I'm confused..

Answer 1

1/3

Explanation:

probability = favorable events / total num of events

here total num of events is 3 and favorable is 1 since there is only one odd number.

therefore, p(odd) = 1/3

Answer 2

`\huge\boxed{\bf\:(1)/(3)=0.33}`

Explanation:

Odd numbers are numbers that end with the digits
`\rightarrow 1,3,5,7,9`, whereas even numbers are numbers that end with the digits
`\rightarrow 0,2,4,6,8`.

Here, we can see that,

• 2 & 4 = even numbers = 2 even number cards
• 3 = odd number = 1 odd number card
• 3 = Total number of cards.

Therefore,

Probability of getting an odd number (3) card

= Number of odd number cards / Total number of cards

= ⅓ = 0.33

`\rule{150pt}{2pt}`
