Answer:
0.01 probability of a car rolling over in a crash.
It is very unlikely for a car to roll over in a crash.
Step-by-step explanation:
Let E be any event.
Then, the probability of happening of an event E =
Now here,
Let E1 = The event where cars rolled when they crashed
E2 = The event where cars did not roll when they crashed
The number of cars that did roll = 83, 600
The number of cars that did not roll = 5,127,400
So, total number of cars taken into account for any event
= 83, 600 + 5,127,400 = 5,211,000
So, P(E1) = 83, 600 / 5,211,000 = 0.01
Hence there is 0.01 probability of a car rolling over in a crash.
and P(E2) = 5,127,400 / 5,211,000 = 0.98
Since P(E2) is way way more than that of P(E1)
Hence, it is very unlikely for a car to roll over in a crash.
