Question

Find the probability that a number selected at random from the numbers 3, 4, 4, 4, 5, 5, 6, 6, 6, 7 will be their mean.

Answer 1

Answer:

Step-by-step explanation:

Here mean = 5

P(E) = favourable outcomes ÷ total outcomes

= 2/10

= 1/5 = 0.2

Answer 2

Answer:

arithematic mean is the average of the frequency

AVERAGE =sum of all frequencies / total no of frequencies

Mean=3+4+4+4+5+5+6+6+6+7/10

mean=50/10=5

PROBABILITY = No of favourable outcomes/total no. of outcomes

P(E)=2/10

P(E)=1/5
