Answer:
look below
Step-by-step explanation:
The probability of each of the cards can be found by dividing each of them by the sum of all the numbers:
P of picking card with star:
25/50=0.5
Card with square:
15/50=3/10=0.3
Card with circle: 10/50=1/5=0.2
We can then put these values into parts a,b,c, and d:
a) 3/10 chance or 30%
b) 1/5 chance or 20%
c) 1/2+1/5=7/10 chance or 70%
d) 1-0.3-0.2=1/2 chance or 50%
Answer:
93
Step-by-step explanation:
Line EJ is a straight line, with Line DC cutting through it. So 180 = Angle DCJ + Angle DCE. So Angle DCE = 48. Triangles are equal to 180°. So 180 = ? +39 +48. So ? = 93
Answer:
$500
Step-by-step explanation:
