Answer:
probability of getting exactly 500 heads= 1
Step-by-step explanation:
If a coin is tossed, the probability of obtaining a head = 0.5
If a coin is tossed, the probability of obtaining a tail= 1- probability of obtaining a head
If a coin is tossed, the probability of obtaining a tail=1-0.5
If a coin is tossed, the probability of obtaining a tail=0.5
So if 1000 coin are tossed, the probability of getting exay 500 heads which is already the half of 1000 is 1
Step-by-step explanation:
Take n common
n(n²+2n-15)=0
now factorise the quadratic one as n when goes to RHS it becomes zero
n²-3n+5n-15=0
n(n-3)+5(n-3)=0
n=3,-5
Answer:
94 stickers
Step-by-step explanation:
50 + 33 + 11 = 94
1. We will multiply 2 * 27 = 54 and then divide by 3, 54/3 = 18
2. We can multiply across 1/2 * 2/3 = 2/6 = 1/3
3. We can multiply across 2/9 * 3/5 = 6/45 = 2/15
4. We can multiply across and get 6
5. 1 3/4 is equal to 7/4
We can multiply across 7/4 * 5/7 = 35/28
