Question

Jade spun a spinner 50 times and recorded her results in the table below. Number on the spinner 1 2 3 4 Frequency 15 10 5 20 What is the experimental probability for the spinner to land on 4?

Answer 1

Sample space = 1 , 2 , 3 , 4

Frequncy of :

1 = 15

2 = 10

3 = 5

4 = 20

Toal spin = 50

$p = \frac{no \: of favourable \: outcomes}{total \: no \: of \: outcomes}$

P ( Land on 4 ) =

$\frac{20}{50}$

P = 2/5
