Answer:
a) 
b) 
Step-by-step explanation:
Conditional probability is the probability of one event occurring with some relationship to one or more other events.
The total probability rule (or the Law of Total Probability) breaks up probability calculations into distinct parts. P(AUB)=P(A)+P(B)-P(A and B)
The general multiplication rule formula is: P(A ∩ B) = P(A) P(B|A)=P(B)P(A|B)
We have the following probabilities:
Part a
We can use this multiplication rule:
For this part we want this probability:
And if we replace we got:
Part b
For this part we want the probability of one event in last year OR one event on the current year, so we can use the probability addition of events:
And for our case we have:
Answer:
The first click beetle reaches a maximum height of 2.25 feet. From the graph, you can see that the second click beetle reaches a maxium height of between 1.5 and 1.6 feet. So, the first click beetle went higher.
Answer:
6 5/12
Step-by-step explanation:
Given the expression :
4 2/3 + 1 3/4
The sum of the numbers :
4 2/3 + 1 3/4
14/3 + 7/4
L.C.M of 3 and 4 = 12
(56 + 21) / 12
77 / 12
= 6 5/12
Answer:
y = -3
Step-by-step explanation:
5y = 3y - 6
2y = -6
y = -3
The answer is letter A. A meter has nearly the same value to a yard, one yard approximately amounting to 1.09361 meter. The rest of the other measures are far from meter's value in distance.
