Question

Ram put some buttons on the table. There were 4 blue, 7 red, 3 black and 6 white buttons in all. All of a sudden, a cat jumped on the table and knocked out one button on the floor. What is the probability that the button on the floor is blue?

Options

• `7/20`

• `3/5`

• `1/5`

• `1/4`

Answer 1

`bb(1/5)`

Explanation:

Probability = `"Number of blue buttons on the table"/"Total number of buttons on the table"`

= `4/20`   ...[Divide both numerator and denominator by 4]

= `1/5`
