Answer:
5(m+n)
Step-by-step explanation:
Parenthesis are grouping symbols and can be used to separate factors like 5(m+n). The factor which 5m and 5n share in common is 5. This is called the greatest common factor since it multiplies into each term. It can be removed from each term and written as 5(m+n).
(a)
You have a 10/26=5/13 chance of picking a red bulb with the first try. If you succeed, you'll have 25 bulbs remaining, 9 of which will be red, leading to a probability of 9/25 for the second pick to be red.
This means that the probability of picking two consecutive reds is
(b)
All the other answers will follow the same logic: you have again a 5/13 probability of picking a red bulb as the first bulb, then you'll have 25 remaining bulbs, 9 of which will be yellow. So, the probability of picking a red and then a yellow bulb is again
(c)
You'll have 9 yellow bulbs out of 26 with the first pick, and 10 red bulbs out of 25 with the second pick. So, the probability of picking a yellow and then a red is
(d)
Putting together (b) and (c), we can see that the probability of having a red and a yellow bulb is 9/65, no matter in which order the red and the yellow will appear.
I think it’s -3 1/3 because if you count your lines after -3 to -2 you get 3 and it’s on the first line so 1/3! Hope this makes sense :)
