Answer 1

hiii....... friends

A die was rolled 100 times and the number of time 6 came up was noted. If the experimental probability calculated from this information is 2/5, then how many times 6 came up? Justify your answer.

2 \div 5 = x + \div 100 \\ x = 2 \div 5 \times 100 \\ x = 40

Where x is no of times 6occured

Answer:

Step-by-step explanation:

Mark it as brainliest..

Here, total number of trials = 100

Let x be the number of times occuring 6.

We know, Probability of an ever = Frequency of the event occuring / Total number of trials

⇒ x / 100 = 2 / 5 [∵ Probability is given]

⇒ x = 40

Answer 2

Answer:

40 times

Step-by-step explanation:

total no. of outcomes= 100

probability of 6= 2/5

P(6)= number of times 6 came up

         total no. of outcomes

=2= number of times 6 came up

 5                       100

=200=5(number of times 6 came up)

=40=number of times 6 came up
