She bought 12, so there is a total of 12 grams.
If she ate half of it, you divide by 2.
12/2= 6 grams
Consider, please, the suggested option.

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:
0.027 to the nearest thousandth.
Step-by-step explanation:
There are 14 marbles in the bag, so:
Prob( a blue on the first draw) = 5/14.
Prob( a blue on the 2nd draw) = 4/13.
Prob( a blue on the 3rd draw) = 3/12 = 1/4.
So the required probability is 5/14 * 4/13 * 1/4
= 20/ 728
= 0.02747.
