Question

Min is about to roll a six-sided number cube. What is the experimental probability that she will roll an even number based on her previous trials?A) 0.25
B) 0.43
C) 0.5
D) 0.67

Answer 1

Answer:

Therefore the experimental probability that she will roll an even number is

C ) 0.5

Step-by-step explanation:

Let S be the sample space for the given experiment that to Roll six sided number Cube

∴ S ≡ { 1, 2, 3, 4, 5, 6}

∴ n(S) = 6

Let 'A' be the event of experiment that she will roll an even number

∴ A ≡ { 2, 4, 6 }

∴ n(A) = 3

To Find:

P(A) = ?

Solution:

We know that for any experiment probability is given by

$\textrm{probability of the experiment}=\dfrac{\textrm{number of favourable outcomes}}{\textrm{total number of outcomes}}$

Substituting the values we get

$P(A)=\frac{n(A)}{n(S)} =\frac{3}{6} =\frac{1}{2} =0.5$

Therefore the experimental probability that she will roll an even number is

C ) 0.5
