------------------------------------------------------------
Define the numbers
------------------------------------------------------------
First the first odd integer be x.
1st odd = x
2nd odd = x + 2
3rd odd = x + 4

------------------------------------------------------------
Form the equation and solve for x
------------------------------------------------------------
5(x + 4) - 94 = x + 2
5x + 20 - 94 = x + 2
5x - 74 = x + 2
5x - x = 2 + 74
4x = 76
x = 19

------------------------------------------------------------
Find the 3 consecutive integers
------------------------------------------------------------
1st = x = 19
2nd = x + 2 = 19 + 2 = 21
3rd = x + 4 = 19 + 4 = 23

------------------------------------------------------------
Answer: The 3 consecutive odd numbers are 19, 21 and 23

For each day in New England, the probability that it is mostly cloudy is 0.10 . Cindi is planning to go leaf watching, and her f
kolbaska11 [484]

Answer:

0,37

Step-by-step explanation:

It will be easier if we noun the events.

A= Cindi's friend comes to England.

B= New England is mostly cloudly.

We are searching the probability of just A doesn´t happen or just A happens but not B.

The probability of A doesn´t happen is one minus the probability of A:

=(A^{|} )=1-P(A)=1-0.7=0.3

The events A and B are independent for this reason the probability than both occurs is the product of the probability of each event. It means:

P(A \cap B)= P(A)P(B)=0.1*0.7=0.07

The probability of A doesn´t happen or A and B happen is:

P(A^{|} \cup (A \cap B))= P(A^{|} )+P (A \cap B)-P(A^{|} \cap A\cap B)=0.3+0.07-0=0.37

Conclusively we have to rest the probability of A doesn´t happen and A and B happen, but A happens and doesn´t happen and the same time is impossible. For this reason, we have the same result.

P(A^{|} \cup (A \cap B))-P(A^{|} \cap A\cap B)=0.37-0=0.38

Then the probability either Cindi's friend does not come to New England, or she does come but it is mostly cloudy is 0.37
