Instead of plugging in
and
right away, notice that

and now evaluating this expression at the two given values is easier, if only a little:

2 blue, 4 green, 3 white....total of 9 chips
P(blue) = 2/9
replacing
P(green) = 4/9
P(both events happening) = 2/9 * 4/9 = 8/81 <==
Answer:
20.
Given, complex number is 10+5i .
We need to find sum of the given complex number and its conjugate. The conjugate of 10+5i is 10-5i. Therefore, the sum will be 10+5i+10−5i=20.
The answer is 24 guppies. First find the volume of the tank, then divide that volume by 576 (you should get 8), then you multiply 3 guppies by 8 to get 2e
