A:21/72
B:11/17
C:1/3
D:12/17
$4500, 9%, 3.5 years
Step-by-step explanation:
Principle (P) =$4500
Rate(R) =9%
Time(T)=3.5yrs
We know,
SI=P×T×R/100
=4500×3.5×9/100
=$1417.5
Answer:
12
Step-by-step explanation:
9x4-(2x12)
= 36-24
= 12
Answer: The required value of is 0.6.
Step-by-step explanation: Given that A and B are two events such that
We are to find the value of
From the laws of probability, we have
Thus, the required value of is 0.6.
Answer: 0.6
Work Shown:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.5 + 0.4 - 0.3
P(A or B) = 0.9 - 0.3
P(A or B) = 0.6
