Answer:
3/4
Step-by-step explanation:
Probability is the likelihood of an event.
No.of favourable outcomes/ Total no. of outcomes
Probability of coin selection : [Both coins have equal likelihood of being chosen]
- Prob( Coin A Selection) = 1/2
- Prob (Coin B selection) = 1/2
Probability of head & tail by both coins :
- Prob (Head / Coin A) = 1/4
- Prob (Tail / Coin A) = 1 - [ P (Head/Coin A) ] = 1 - 1/4 = 3/4
- Prob (Head / Coin B) = 3/4
- Prob (Tail / Coin B) = 1 - [ P (Head/Coin B) ] = 1 - 3/4 = 1/4
Probability of getting head by Coin A : Prob (Coin A) & Prob (Head/CoinA) = 1/2 x 1/4 = 1/8
Probability of getting tail by Coin A : Prob (Coin A) & Prob (Tail/CoinA) = 1/2 x 3/4 = 3/8
Probability of getting head by Coin B : Prob (Coin B) & Prob (Head/CoinB) = 1/2 x 3/4 = 3/8
Probability of getting tail by Coin B : Prob (Coin B) & Prob (Head/CoinB) = 1/2 x 1/4 = 1/8
Probability 'The guess [head from coin B, tail from coin A] :
Prob (Coin A) & Prob (Tail/CoinA) or Prob (Coin B) & Prob (Head/CoinB)
= 3/8 + 3/8 = 3/4
Answer:
it's 1
Step-by-step explanation:
when one is multiplied by three times.it gives us three and its difference result negative five 3–8 = -5
Answer:
2iroot2
Step-by-step explanation:
Y = mx + b
m = (y2 - y1)/(x2 - x1)
y = (26,600 - 18100)/(20 - 10)x + b
y = 850x + b
18100 = 850(10) + b
b = 9600
R(x) = 850x + 9600
