Question

The face of dice bear the number 1,2,3,5,7,9,11 the dice is rolled find the probability getting perfect square number of upper faces of dice​

Answer 1

Answer:

1/7

Step-by-step explanation:

because according to it there are total 7 number and the perfect square is only 3

so.

according to formula

= 3/7

Answer 2

Answer:

1/7

Step-by-step explanation:

If the face of dice bear the number 1,2,3,5,7,9,11  then, on rolling the dice the sample space is

S={1,2,3,5,7,9,11}

The set of perfect squares is

S*={9}

The cardinality of a set is a measure of a set's size, meaning the number of elements in the set.

n(S)=7

n(S*)=1

the probability getting perfect square number of upper faces of dice​ is computed as

$Prob=\frac{n(S^*)}{n(S)}=\frac{1}{7}$

1/7
