The question focuses on "if the student is known to be a boy..." we would obviously know that we would focous on only the total of the boys.
We have the formula for the probability of an event of happening which we would call event A (a boy being left-handed). P(A)= number of favorable outcomes/ total number of possible outcomes. The left-handers would go in the favorable outcomes since we want the probability of a boy being left handed and we would place the total boys in the total number of possible outcomes since all of them are going to be the one to be randomly picked. 50 left-handed/ 200 total boys. We have our fraction that is 50/200 as the probability but we can simplify it! We simplify 50/200 to get 1/4!!! 1/4 is the probability of a boy being picked that is left-handed!
Hope this helps!
Answer:
The correct answer is C. 224
Step-by-step explanation:
Sn = n/2 (2*A1 +d(x-1))
S7=7/2(2*17+5(7-1))
S7=7/2(34+30)
S7=7/2(64)
S7=7*64/2
S7=7*32/1
S7=224

Let us assume the amount of money invested in CD = x
Then
Amount of money invested in savings bond = 6000 - x
Percentage of interest in CD = 4%
Percentage of interest in savings bond = 7%
Amount of interest gained in 1 year = $360
Now
0.04x + [(6000 - x) * 0.07] = 360
0.04x + 420 - 0.07x = 360
0.03x = 60
x = 2000
Then
Amount of money invested in the CD account = $2000
Amount of money invested in savings bond = 6000 - 2000
= 4000 dollars
