We are given frequency distribution in the question
to find the probability distribution from frequency distribution we need to divide frequency by total number of observations.
Here, total number of observations are 6+10+7+5=28
so , we will have probability distribution table as
X 0 1 2 3
P(x) .21 .35 .25 .17
probability distributiuon describes all possible values that a random variable can take within a given range.
frequency distribution is the presentation that presents number of observation in given interval.
Answer:
30
Step-by-step explanation:
30/-5=-6
due to integer rules the number would be negative
Answer:
area of trapazoid= 1/2 × b× h
so = 1/2×9×15
=1/2×135
=67.5cm
Answer:
your answer should be 45
Step-by-step explanation:
Answer:
75% of students voted for the athlete
Step-by-step explanation:
total number of students 24+8 = 32
24 out of 32 students chose the athlete
24/32 simplified = 3/4
3/4 = 75%
