50. a bag contains five yellow tickets numbered one to five. the bag also contains five green tickets numbered one to five. you randomly pick a ticket. it is green or has a number greater than four. find the probability of this occuring. (2.0 points)

60%

Step-by-step explanation:

There is a one in two chance of picking up a green ticket, since there are only two colours. The only number greater than 4 in this pack is 5. The chances of picking up a five are 2 out of 10. The chances of picking up a green 5 is 1 out of 10.

These events aren't mutually exclusive, because you can pick up a green 5 , which would constitute both events.

The probability of an OR function of events which aren't mutually exclusive is as follows:

Where:

A: green card

B: number 5 card

C: number 5 green card.

Thus:

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
