Answer: first part is 2 then 0, after, its “are two real solutions” on edg, yw
Step-by-step explanation:
I looked at the other one you just asked and I couldn't figure it out. I understand this one.
Laney goes from 1 to 5, Gus from 1 to 6, Gus has the greater range. TRUE
Just eyeballing the data, Gus's median is 5, Laney's is 3. TRUE
Laney's data is more symmetrical, closer to the usual bell shape. Gus is heavily weighted toward the higher values, less symmetrical. TRUE

Answer:
The events are not mutually exclusive because the P(A and B)=0.1 not 0
Step-by-step explanation:
Mutual exclusive events are those that can't happen at the same time.For example Tossing a coin, Head and Tail are mutually exclusive events because you can't get a Head and a tail at the same time.Another example is turning left and turning right are mutually exclusive because you can't do both at the same time.
If events are mutually exclusive, they can happen at the same time.
Mathematically,the probability of mutual exclusive events follows;
P(A and B)=0 ------------The probability of A and B together equals 0
P(A or B) = P(A)+P(B)-----The probability of A or B equals the probability of A plus the probability of B.
In this question you are given;
P(A)=0.3
P(B)=0.6
P(A or B) =P(A) + P(B)= 0.3+0.6 =0.9
0.9≠0.8 thus the events are not mutually exclusive.
First, get the common denominator. Do this by multiplying 5/10 by 10
35/100 + 50/100 = 85/100
Then,simplify :
17/20
Hope this helps!
