Answer:
20
Step-by-step explanation:
The expected value of a toss is:
E(X) = (0.10) (3) + (0.30) (1) + (0.60) (0)
E(X) = 0.6
If she scores an average of 0.6 points per toss, then the expected number of tosses needed to get 12 points is:
12 / 0.6 = 20
Using a random number table, we can assign digit 0 as a 3-point hole, digits 1-3 as a 1-point hole, and digits 4-9 as no points. Read the digits and add the points until you get 12 points. The number of digits read is the number of beanbag tosses.
Answer: Andy should invest RS. 2784.19 for 12 years .
Step-by-step explanation:
Since we have given that
Amount = Rs. 5000
Time = 12 years
Rate of interest = 5%
So, We need to find the sum:
Using "Compound interest" , we get :
Hence, Andy should invest RS. 2784.19 for 12 years .
Rule is : plus 5
Volume is 36
The probablility is 1/2 or 0.50 % chance.
