Answer:
0.2503
Step-by-step explanation:
To solve this , we use the Bernoulli trial equation.
Now, there are 10 questions with 4 options each. The total number of options is thus = 10 × 4 = 40 options
There are only 10 correct answers however. The probability of picking a correct answer is thus 1/4 or 0.25
Now we know there are 30 wrong options. The probability of picking a wrong option is 30/40 or 0.75
To answer 3 questions correctly, it means she would answer 7 wrongfully.
Now to complete the parameters for the bernoulli trial, we know she is making 3 correct choices. Now the number of ways to select three correct choices out of 10 is 10C3
Computing the Bernoulli trial, we have :
(10C3) × (0.25)^3 × (0.75)^10
= 0.2503
Answer:
Amount June get = £45
Step-by-step explanation:
Given:
Total amount divided = £150
Amount Nick get = 2 x Amount June get
Amount June get = 3 x Amount Sushil get
Find:
Amount divided between Nick June and Sushil
Computation:
Assume;
Amount Sushil get = a
Amount June get = 3 x Amount Sushil get
Amount June get = 3a
Amount Nick get = 2 x Amount June get
Amount Nick get = 2 x 3a
Amount Nick get = 6a
Amount Sushil get + Amount June get + Amount Nick get = Total amount
So,
a + 3a + 6a = 150
10a = 150
a = 15
So,
Amount Sushil get = £15
Amount June get = 3a
Amount June get = 3 x 15
Amount June get = £45
Amount Nick get = 6a
Amount Nick get = 6 x 15
Amount Nick get = £90
Here's my work. Hope it helps.
To find volume you use the formula
Volume=base× height
the base is 6×5
he height is 11
Volume=(5×6)×11
Volume=30×11
Volume=330 cubic centimeters
