A jar contains 8 marbles numbered 1 through 8. an experiment consists of randomly selecting a marble from the jar, observing the
zepelin [54]
There are 8 possible outcomes for a marble being drawn and numbered. 
{1,2,3,4,5,6,7,8}
There are 4 possible outcomes for a card being selected from a standard deck.
{ <span>hearts, diamonds, clubs, spades}
So the number of outcomes in the sample space would be 8 x 4 = 32.

In the event "an even number is drawn", there are only 4 possible outcomes for a marble being drawn, {2,4,6,8}, whereas there are still 4 possible outcomes for a suit. So the number of outcomes in the event is 4 x 4 = 16.

</span><span>In the event "a number more than 2 is drawn and a red card is drawn", there are 6 possible outcomes for the marble being drawn, {3,4,5,6,7,8}, whereas there are only two possible suits for a card being selected as red, {heart, diamond}. So the number of outcomes in this event is 6 x 2 = 12.

In the event </span><span>"a number less than 3 is drawn or a club is not drawn", the number drawn could be 1 or 2 whereas a spade/heart/diamond could be selected. So the number of outcomes is 2 x 3 = 6.</span><span>

Compute (3+4i) +(7 − 20i).
Sveta_85 [38]

Answer:

10 -16 i

Step-by-step explanation:

given,

(3+ 4 i) + (7 − 20 i)

for the given complex number

if the number is added of subtracted the real part will add or subtract to the real part and imaginary will add or subtract to the imaginary part.

now

                = (3+ 4 i) + (7 − 20 i)                                  

               = (3 + 7) + (4+(-20)) i                      

                = 10 + (-16) i                      

                = 10 -16 i                              

so, the given answer will be 10 -16 i
