If the probability of a win is 0.02, and the probability of a draw is 0.8, what is the probability of a loss?
atroni [7]
A probability is a number between zero and one. 

There are 3 options win, lose or draw. 
This means that (win + loss + draw = 1)

From the information given you know:
Win = 0.02
Draw = 0.8 

So: 0.02 + loss + 0.8 = 1 
Therefor loss = 1 - 0.8 - 0.02 
loss = 0.18 
final answer ^

Someone help me with this question ASAP please!!
Sever21 [200]

Answer:

A

Step-by-step explanation:

Because 7000*1.09= 7630

and 5000*1.11= 5550 which are both equal to the amount each account will have after one year where they have gained interest.

In the first account 7630-7000=630 and the second 5550-5000=550

which is how much each gained in interest. together that makes 630+550=1180 in interest.
