Assume that there are 2 trials.

x = 2 where x represents the number of successes.

which probability matches the probability histogram?

round the answer to one decimal place.

p(success)=0.2

p(success)=0.3

p(success)=0.7

p(success)=0.8

P(success)=0.2 matches the probability histogram.

Step-by-step explanation:

Formula :

Where X represents the number of successes.

p represents probability of success .

1-p represents probability of failure.

Now when X= 0 the  probability is 0.64 (Using histogram )

So,

So, the probability of success = 0.2

Hence P(success)=0.2 matches the probability histogram.

there is no grid

step-by-step explanation:

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200
