So, she will get the complete money
Answer:
-First player wins:
![P(HT) = p-p^2](https://tex.z-dn.net/?f=P%28HT%29%20%3D%20p-p%5E2)
-Neither player wins:
![P(HH) + P(TT)= 2p^2 -2p +1](https://tex.z-dn.net/?f=P%28HH%29%20%2B%20P%28TT%29%3D%202p%5E2%20-2p%20%2B1)
Step-by-step explanation:
Applying the 4 step method:
Step 1: Identify events for which probability is to be determined:
- First player wins: First coin is heads, second coin is tails (HT)
- Neither player wins: Both coins are heads or both coins are tails (HH or TT)
Step 2: Calculate total number of possible outcomes:
Four possible outcomes: HH, HT, TT, TH
Step 3: Calculate probability of each event
Since the probability of a coin coming up heads is 'p':
![P(HH) = p^2\\P(TT) = (1-p)^2 = 1 - 2p +p^2\\P(HT) =p*(1-p) = p-p^2\\P(TH) = (1-p)*p = p-p^2\\](https://tex.z-dn.net/?f=P%28HH%29%20%3D%20p%5E2%5C%5CP%28TT%29%20%3D%20%281-p%29%5E2%20%3D%201%20-%202p%20%2Bp%5E2%5C%5CP%28HT%29%20%3Dp%2A%281-p%29%20%3D%20p-p%5E2%5C%5CP%28TH%29%20%3D%20%281-p%29%2Ap%20%3D%20p-p%5E2%5C%5C)
Step 4: Add probability of each event
-First player wins:
![P(HT) = p-p^2](https://tex.z-dn.net/?f=P%28HT%29%20%3D%20p-p%5E2)
-Neither player wins:
![P(HH) + P(TT)= p^2 + 1 - 2p +p^2\\\\P(HH) + P(TT)= 2p^2 -2p +1](https://tex.z-dn.net/?f=P%28HH%29%20%2B%20P%28TT%29%3D%20p%5E2%20%2B%201%20-%202p%20%2Bp%5E2%5C%5C%5C%5CP%28HH%29%20%2B%20P%28TT%29%3D%202p%5E2%20-2p%20%2B1)
Answer:
Lebeled Price of watch = Rs. 2000
Selling price pf the watch = Rs. 1600
Step-by-step explanation:
- ∴ S = L - 20% L
- ∴ S = 0.8 L ..... (1)
- ∴ S = P + (1/3)P
- ∴ S = (4/3) P ..... (2)
- As we know, P = 1200
- ∴ S (4/3) × 1200
- ∴ S = Rs. 1600
- 1600 = 0.8L
- ∴ L = 1600 ÷ 0.8
- ∴ L = Rs.2000
- ∴ Lebeled Price of watch = Rs. 2000
- Selling price pf the watch = Rs. 1600
Answer:
It is D
Step-by-step explanation:
Distribute:
=(4)(5m)+(4)(3)+2m
=20m+12+2m
Combine Like Terms:
=20m+12+2m
=(20m+2m)+(12)
=22m+12
Step-by-step explanation:
1) 3x-2=-1 is equal to x=1/3
2) y = -2 That where you start on you y-axis.
3) x = 1/3 That's your slope.. Starting from -2 (go up 1 unit then to the right 3 units.) That forms a line.
