(must round down for population)
N^2 because 2n is the same as n+n, but n^2 is the same as the product of n and n
Answer:
A is a subset of B i believe that's the answer
Answer:
y-intercept = 275
x-intercept = 125
Step-by-step explanation:
The y-intercept is the point on your line where x=0. On this line, the y-intercept is the point (0,275) (x,y)
The x-intercept is the point on your line where y=0. On this line, the x-intercept is the point (125,0) (x,y)
Answer:
1) Event A = 2/3
Event B = 1/2
2) 1/2
Step-by-step explanation:
1)
Event A :
No. we need on dice = 4
Total numbers on dice = 6
Hence sample space of the event = 6
P( getting 4) = 4/6 = 2/3
Event B :
A coin has a head & a tail.
Hence sample space of the event = 2
But as we need tail only ,
P ( getting Tail ) = 1/2 [ if only tossed once ]
2)
Total numbers on a die = 6
Total no. of odd numbers on die = 3 (∵ 1 , 3 & 5 are odd )
Sample space of this event = 6
P (getting an odd number) = 3/6 = 1/2
