60 because 2:4 is 1/2, and when you divide by a fraction, you multiply by the reciprocal (2/1 instead of 1/2) which would be 60 in this case.
Answer:
1,900,800
Step-by-step explanation:
Answer: So the number of outcomes with exactly 4 tails is 720/2/24 = 15. Finally we can now calculate the probability of getting exactly 4 tails in 6 coin tosses as 15/64 = 0.234 to 3 decimal places.
Times the second equation by 2 to get y=9x-33 and then subtract
3x+2(x-1)-4
=3x+2x-2-4
=5x-6
Ans: Option A.
