Question

If we buy 20 pickles what is the experimental probability of winning 5 or more tickets

Answer 1

`Pr = 0.66`

Explanation:

Given

See attachment for complete question

Required

`P(x \ge 5)`

From the attachment, we have:

`S = 2 + 8 + 4+20+21+19+17+5+2+2`

`S =100` ---- the sample size

Next, we list out all outcomes more than or equal to 5.

i.e.

`x \ge 5`

5 is represented with the vertical blue rectangle (with frequency 21).

So, the other elements are to the right of frequency 21.

So, we have:

`x \ge 5 = 21+19+17+5+2+2`

`x \ge 5 = 66`

The probability is then calculated as:

`Pr = (x \ge 5)/(S)`

This gives

`Pr = (66)/(100)`

`Pr = 0.66`
