Question

Amy reached into a bag, recorded the color of the tile she picked, returned the tile and drew again. These are the tiles she has drawn so far:

red, red, blue, yellow, blue, red, green, red, blue, green


What is the probability that her next draw will be blue?


Fraction form only


What is the probability that her next draw will NOT be red?

If Amy draws 70 more times with the same tiles from the question above, what probability would you expect a yellow?

Use / for fraction bar if necessary

Answer 1

(a) P(next ball with blue) =
`(3)/(10)` (b) P(Not to be red) =
`1-(2)/(5) =(3)/(5)`

(c) P(drawing 70 times yellow ball) =
`(1)/(10) * 70 = 7`.

Explanation:

Given that,

The total outcomes of the color of tile are :-

Red , Red, Blue, Yellow, Blue, Red, Green, Red, Blue, Green.

From the Question,

Total number of outcomes = 10

(a) What is the probability that her next draw will be blue ?

Red = 4,

Blue = 3,

Green = 2,

Yellow = 1.

P(next ball with blue) =
`(3)/(10)`.

(b) What is the probability that her next draw will NOT be red?

P(Red ball) =
`(4)/(10) = (2)/(5)`

But we have to find

P(Not to be red) =
`1-(2)/(5) =(3)/(5)`

(c) If Amy draws 70 more times with the same tiles from the question above, what probability would you expect a yellow?

P(Yellow ball) =
`(1)/(10)`

drawing it 70 times we get the probability

P(drawing 70 times yellow ball) =
`(1)/(10) * 70 = 7`.
