Answer:
4.4722
Step-by-step explanation:
The following table shows the 36 elements of the sample space of the experiment
From this table we can compute the probabilities
:
P(X = 1) = 1/36
P(X = 2) = 3/36
P(X = 3) = 5/36
P(X = 4) = 7/36
P(X = 5) = 9/36
P(X = 6) = 11/36
So the expected value equals
1P(X=1)+2P(X=2)+3P(X=3)+4P(X=4)+5P(X=5)+6P(X=6) =
= 1/36 + 6/36 + 15/36 + 28/36 + 45/36 + 66/36 = 161/36 =
4.4722
Step-by-step explanation:
18×RM 8= RM 144
13× RM 11=RM 143
RM 144+143= RM 287
are u Malaysian too? coz I'm one hehe
They can rent the boat for 7 hours if u add 50+25×7 it equals $225.
Make bottom number same
4/13 times 10/10=40/130
3/10 times 13/13=39/130
between 40/130 and 39/130
hmm
we can doulbe both (time 2/2 each)
80/260 and 78/260
a ratioal number between is 79/260
