Simplify: -2/5 + 4/3
hoa [83]

Answer:

14/15

Step-by-step explanation:

1. Convert the fractions to have the same denominator

Remember that you can only add fractions with the same denominator

To find the common denominator, find the LCM of 5 and 3 which is 15.

-2/5 * 3/3 = -6/15 and 4/3 * 5/5 = 20/15

-6/15 + 20/15 = 14/15

hope this helps! <3

Answer: 0.5

Step-by-step explanation:

Formula for binomial probability :-

P(x)=^nC_xp^x(1-p)^{n-x}, 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 :-

P(x

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