A "True or False" test has five questions.

Mathematics
1 answer:
Gennadij [26K]4 years ago
4 0

Answer:

5/16.

Step-by-step explanation:

The probability of getting a correct answer on one question is 1/2 and the probability of getting it wrong is  1 - 1/2 = 1/2.

The probability of the first 2 being correct and the next 3 wrong = (1/2)^5 = 1/32.

There are  10  possible combinations of this ( first wrong the 2nd and third right and last  2 wrong,  etc).

So the  required probability is 10 * 1 /32

= 10/32

= 5/16.

What is the value of n in 4n + 2 = 6(1/3n - 2/3)?
inysia [295]

4n + 2 = 6(1/3n - 2/3)?

Use distributed to remove parenthesis


4n+2=6(1/3n)+6(-2/3)

Solve right side

4n+2=2n-4


Subtract 4n from 2n


4n-2n+2=-4

Simplify

2n+2=-4

Subtract 2 from both sides

2n=-4+2

Simplify

2n= -2

Divide both sides by 2

2n/2=-2/2


And solve

N= -1
