Magnet Side Up Magnet Side Down
13
37


The relative frequency of landing magnet side up is
.

The relative frequency of landing magnet side down is
.

Answer 1

1- 0.26

2- 0.74

Answer 2

Hence,

The relative frequency of landing magnet side up is :

0.26

The relative frequency of landing magnet side down is:

0.74

Explanation:

We know that a relative frequency is the ratio of the frequency of an outcome to the total number of outcomes.

We are given an frequency as:

Magnet Side Up Magnet Side Down Total

13 37 50

Hence, the relative frequency is calculated as dividing each of the frequency by total frequency i.e. 50.

i.e. The table is given as:

Magnet Side Up Magnet Side Down Total

13 /50=0.26 37 /50=0.74 50/50=1
