Steve has 11 biscuits in a tin. There are 4 digestive, 5 chocolate and 2 ginger biscuits.
Steve takes two biscuits at random from the tin.
Work out the probability that he chooses two different types of biscuits.

0.89

Step-by-step explanation:

because he has 11 biscuits in total the method of calculating probability is 1- an integer so if the integer is 11 its 1 minus 11 is 0.89

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
