Question

A jar contains 6 red marbles numbered 1 to 6 and 8 blue marbles numbered 1 to 8. A marble is drawn at random from the jar. Find the probability the marble is red or odd numbered.

Answer 1

`P(R\ or\ odd\ Numbered)=5/7`

Explanation:

From the question we are told that:

Number of Red Marble
`n_r=6`

Number of Blue Marble
`n_b=8`

Sample size
`n=n_r+n_b`

`n=6+8`

`n=14`

And

No of red or Odd numbered
`x= 6+4 = 10`

Generally the equation for probability the marble is red or odd numbered. is mathematically given by

`P(R or odd Numbered)=x/n`

`P(R or odd Numbered)=10/14`

`P(R\ or\ odd\ Numbered)=5/7`
