Answer:
D none of the above. I hope it is correct
4x + 6y = 2
Answer:
x = -5/3 and y = 13/9
Step-by-step explanation:
b) 1/5
c) 1/10
d) 1/4
2X+3y=432 and 5x-2y=16
Exactly one tail
At least one tail
All tails
Three heads
By using sample space we can say that complement of 4 heads in the toss of 4 coins is at least one tail .
set of all possible outcomes experiment is called sample space .
To find compliment of 4 heads we will first find sample space Sample space= S
= { HHHH, HHHT, HHTH, HHTT, HTHH, HTHT, HTTH, HTTT, THHH, THHT, THTH, THTT TTHH, TTHT, TTTH, TTTT }
Given case is 4 heads Say A= { HHHH}
Now we can calculate A complement as
A' = S-A
= { HHHH, HHHT, HHTH, HHTT, HTHH, HTHT, HTTH, HTTT, THHH, THHT, THTH, THTT TTHH, TTHT, TTTH,TTTT }- { HHHH}A'={ HHHT, HHTH, HHTT, HTHH, HTHT, HTTH, HTTT, THHH, THHT, THTH, THTT TTHH, TTHT, TTTH,TTTT }
By using sample space we can say that complement of 4 heads in the toss of 4 coins is at least one tail .
