A student solves a problem correctly 40 times out of 72 tries. Based on this data, what is the probability that the student inco

suter [353]

Answer:

The probability of the student incorrectly solves the next problem is 44%.

Step-by-step explanation:

Let E be the event of solving a problem correctly.

Then E' is the event that the problem is solved incorrectly.

Now, recall the definition of probability.

probability of an event = $\frac{number of favorable events}{total number of events}$

So,

p(E) = $\frac{40}{72}$

Also,

p(E) + p(E') = 1 and

p(E') = 1 - p(E)

= 1 - $\frac{40}{72}$

= $\frac{72-40}{72}$

= $\frac{32}{72}$

= $\frac{4}{9}$

= $\frac{4}{9} (100)$

= 44% rounded.

Hence, the probability of the student incorrectly solves the next problem is 44%.

-3(y-5)=24 what is the value of y

Gemiola [76]

Step 1
distribute the -3
-3(y-5)=24
-3y+15=24
step 2
subtract 15 from both sides
-3y =9
Step 3
divide -3 on both sides
y=-3
