The cube has 6 possible outcomes.  The probability of either of
two of them occurring is  2/6  =  1/3 .

The coin has 2 possible outcomes.  The probability of one of them is 1/2 .

The probability of both specified outcomes occurring is

             (1/3) x (1/2)  =  <em>1/6  </em>=  (16 and 2/3) percent

Softa [21]

Answer:

Option C is correct

P(A or B) = 0.65

Step-by-step explanation:

<u>Given: </u>

P(A) =0.5

P(B)=0.30

P(A and B) =0.15

( The probability of the happening of both independent events will be there product) P( A and B ) =P(A).P(B)

<u>Solution:</u>

To find the probability  of the Happening of event A either event B  we will use the following formula

P(A or B) = P(A) + P(B)-P(A and B)

                  = 0.5 + 0.3 - 0.15

                  =0.65
