Answer :
Answer:
probability (x ≤2) = 0.64
Step-by-step explanation:
P(2 or fewer) = probability of 2 or fewer
probability of (2 or fewer) = probability (x ≤2)
probability of (2 or fewer) = probability when x is 0 + probability when x is 1 + probability when x is 2
probability of (2 or fewer) = probability (x =0) + probability of (x =1 ) + probability (x= 2)
probability of (x=0) = 0.09
probability of (x=1) = 0.26
probability of (x =2) = 0.29
probability of (2 or fewer) = 0.09 + 0.26 + 0.29 = 0.64
probability (2 or fewer) = probability (x ≤2) = 0.64
Answer:
[tex] P(X \leq 2)= P(X=0) +P(X=1)+P(X=2)[/tex]
And replacing we got:
[tex] P(X \leq 2)= 0.09 +0.26+0.29 = 0.64[/tex]
And the probability that X would be 2 or lower is 0.64
Step-by-step explanation:
For this case we have the following probability distribution:
x 0 1 2 3 4 5
P(x) 0.09 0.26 0.29 0.20 0.09 0.07
And we want to find the following probability:
[tex] P(X \leq 2)[/tex]
And we can find the probability like this:
[tex] P(X \leq 2)= P(X=0) +P(X=1)+P(X=2)[/tex]
And replacing we got:
[tex] P(X \leq 2)= 0.09 +0.26+0.29 = 0.64[/tex]
And the probability that X would be 2 or lower is 0.64
