Aset of cards includes 15 yellow cards, 10 green cards and 10 blue cards. find the probability of each event when a card is chosen at random not yeallow or green

P(not yellow or green)=\frac{2}{7}[/tex]

Step-by-step explanation:

a set of cards includes 15 yellow cards, 10 green cards and 10 blue cards

Total cards= 15 yellow + 10 green + 10 blue = 35 cards

Probability of an event = number of outcomes divide by total outcomes

number of outcomes that are not yellow or green are 10 blue cards

So number of outcomes = 10

P(not yellow or green)=

step-by-step explanation:   divide the numerator by the denominator to get the decimal

it would still be 193

if divide by 100 then 1.93
