Answer:
P ( not white ball) = 2/3
Step-by-step explanation:
If there are 10 blue balls and 10 black balls and 10 white balls,
10+10+10 = 30 total balls
P(white ball) = white balls/ total balls
= 10/30
= 1/3
P (not getting a white ball) = not white/ total
= (blue + black)/ total
= (10+10)/30
=20/30
2/3
All you have to do is multiply the two numbers together
1.18 x 18.5 = 21.83
Use Pythagoras's theorem.
Now, minus 12 from 15:
15 - 12 = 3,
which you need to square.
So the length of a = 9cm.
You can also do:
Which gets 9.
