A bunch of mixed colored roses has 5 red roses, 3 pink roses, 2 white roses, and 2 yellow roses. What is the probability of drawing a pink rose from this bunch of roses?

the probability of drawing a pink rose from the bunch of roses is 25%

Step-by-step explanation:

assuming that each rose es equally likely to be chosen then the probability of picking one pink rose is

probability = number of pink roses / total number of roses = 3 / (5+3+2+2) = 3/12 = 0.25 (25%)

then the probability is 25%

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
