Answer:
The probability that she rolls a number greater that 4 or a 2 = or 50%
Step-by-step explanation:
Given:
A six sided number cube is rolled labelled from 1 to 6.
To find the probability that she rolls a number that is greater than 4 or a 2.
Solution:
The possible outcomes of rolling a six-sided cube are:
{1,2,3,4,5,6}
Event A:
The favorable outcomes greater than 4 are:
{5,6}
Probability of event A to occur =
Event B:
The favorable outcome is a 2
{2}
Probability of event B to occur =
We find that the two events are mutually exclusive as they have no common outcomes.
Thus, the probability that event A or B occurs ( P(AUB) ) can be given as:
⇒
Since denominators same, so we add the numerators.
⇒
Reducing it to simpler fraction:
⇒ (Answer)
Thus, the probability that she rolls a number greater that 4 or a 2 = or 50%
Answer:
the percentage is 55/100*100=55%
Step-by-step explanation:
the segment of the square is 40/4=10 cm
so the area of the square is 10^2=100cm^2
the shaded area = the area of the square - the sum of the areas of the triangles inside the square
100- (10*6/2+10*3/2)=100-(30+15)=55 cm^2
Answer:
Step-by-step explanation:
Part a is AB and CD because those lines are symmetrical.
Part D is the angle is the same as A so D is 30 as well. then for b and c since those are the same you take 180-30 to get 150 for both angles
