Answer:
0.16 or 16%
Step-by-step explanation:
an easier way to work this out is to convert these decimals into percentage. to do this, multiply the number by 100:
0.2 x 100 = 20%
0.64 x 100 = 64%
a percentage is out of 100 (probability of a win = 20/100 = 1/5) so to work this out, you just have to subtract the percentages that are known from 100:
100% - 20% = 80%
80% - 64% = 16%
∴ the probability of a loss = 16% or 0.16 as a decimal.
<u>Another way to work this out</u> is to add together the amounts that are given then work out what number needs to be added to = 1
0.2 + 0.64 = 0.84
0.84 + <u>?</u> = 1
0.84 + <u>0.16</u> = 1
∴ the probability of a loss = 0.16
HOPE THIS WAS HELPFUL :-)
