The answer would actually be a 110 units because the bottom left corner had 20 units and the bigger square had 90.
1// Flip the second fraction [RECIPROCAL]
2// Multiply bottom of fraction by whole number, add 1 to bottom of whole number.
3// Simplify.
A: 100 cm³
This is because the others can be multiplied by something 3 times to get it, but A can not.
Answer: 0.5
Step-by-step explanation:
Formula for binomial probability :-
, where P(x) is the probability of getting success in x trials , n is the total number of trials and p is the probability of getting success in each trial.
Given : The number of trails : n=7
The probability of success for each trial : p=0.5
Now, the probability that the number x of correct answers is fewer than 4 will be :-

Hence, the probability that the number x of correct answers is fewer than 4 = 0.5
