Let's try addition
3-9=-6
-6+18=12
12-8=4
4+16=20
doesn't seem to be a pattern
try mulitpcation
3 times -2=-6
-6 times -2=12
12 times 1/3=4
4 times 5=20
can't see a pattern
dunno what the patttern is
unless you mistyped th equestio
Okay so first since there are 4 red marbles, 4 blue marbles, and 12 yellow marbles, you add them together so the whole total would be 20 marbles now. Since there are 4 marbles, the probability of her pulling it out would be 4/20. So now that she took 1 red marble away, we have 19 marbles left. So now that has been finished, she 1 more yellow marble away so now we have 12/19. Now that it's completed you multiply the two, and now you should have 12/95, divide 12/95 and you'll get 0.126315789 in other words rounded that too the nearest hundredth and you'll get 0.13
Answer:
1.75
Step-by-step explanation
from the 5 you taking away 3 1/4 which when doing that it gives you the total of 1.75
There are 49 total marbles, the chance of you getting a red is 17/49, and if you don’t replace the marble and pull out another one, the probability of that being red is 17/49*16/48=17/147. That’s approximately a .12% chance.
16/48=1/3
Answer:
a) 
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that A and B are independent events
P(A∩B) =P(A) P(B)
we will use the conditional probability
