Simplify the following expression: (35 + 24 )/(22 + 31 )

1.11

Step-by-step explanation:

35 + 24 = 59

22 + 31 = 53

59 ÷ 53 ≈ 1.11

Have a good day :)

the probability of the given event.

(a) The marble is red

answer is : 10/18=5/9

(b) The marble is odd-numbered

answer is : (5+4)/18=9/18=0.5

(c) The marble is red or odd-numbered

answer is : (10+9-5)/18=14/18=7/9

(d) The marble is blue or even-numbered

answer is : (8+9-4)/18=13/18

Suppose that A and B are two independent events for which P(A)=0.28 and P(B)=0.84. Find each of the following:

A. P(A|B)=0.19

B. P(B|A)=0.666

C. P(AandB)=0.6

D. P(AorB)=0.2

Two fair dice, one blue and one red, are tossed, and the up face on each die is recorded. Define the following events:

E:{ The difference of the numbers is 3 or more }

F:{ The sum of the numbers is even }

Find the following probabilities:

(a) P(E)= 1/6

(b) P(F)=1/2

(c) P(E∩F)=1/12

Are events E and F independent?

A. yes

B. no

=One of the most important concepts in probability is that of independent events. Two events E and F are independent if the occurrence of event E does not affect the probability of event F.
