Theoretical probablity=desiredoutcomes/totalpossibleoutcomes
desired=number of white marbles=20
total possible=red+blue+white=30+50+20=100
so theoretical probablity=20/100=2/10=0.2=20%
Answer: The experimental probability that she will roll an even number=
Step-by-step explanation:
We know that the probability for any event is given by6;-
In a dice, the total even numbers (2,4,6)= 3
Therefore, the probability that she will roll an even number will be given by:-
Hence, The experimental probability that she will roll an even number=
Answer:
-10.5
Step-by-step explanation:
2 x (-5.25) = -10.5
Answer:
m∠CPD = 129.75°
Step-by-step explanation:
m∠APD + m∠APB = 180 since the angles are supplementary
x + 1 + 3x - 18 = 180
4x - 17 = 180
4x = 197
x = 49.25
m∠APB = 3(49.25) - 18 = 129.75
m∠APB = m∠CPD because the angles are vertical angles
m∠CPD = 129.75°
