Number of outcomes when flipping a coin = 2
Favorable outcome is landing on head.
So,number of favorable outcomes = 1
Probability of getting a head when flipping a coin =

Number of outcomes when rolling a dice = 6
Favorable outcomes are rolling 4,5 or 6.
So,number of favorable outcomes = 3
Probability of getting 4 or a bigger number when rolling a dice =

Thus the probability of getting a head when flipping a coin and getting a number equal to or greater than 4 when a dice is rolled =
So, option A gives the correct answer
Hello here is a solution :
Well the equation for slope is

number 5

which means the slope is
Well 25 seats are available so 25/250 equals 0.1 or
10%
Acceleration = 9.8 m/s
OR you might use 10m/s at your level (i'm not sure which)
