The possible outcomes that will be obtained are:
Option: C
C) 12
Step-by-step explanation:
When we flip a coin the outcomes that are obtained are:
{H,T}
Now, the possible outcomes that is obtained on flipping a die after flipping a coin are:
{(H,1),(H,2),(H,3),(H,4),(H,5),(H,6),(T,1),(T,2),(T,3),(T,4),(T,5),(T,6)}
Hence, the total number of possible outcomes that are obtained on flipping a coin and rolling a six-sided die are:
12
Also the tree diagram of these possible outcomes is attached to the answer.
Answer:
35 [$]
Step-by-step explanation:
1) if Peter's sum is p and Jacky's is j, then the ratio 5:2 in the condition can be written j/p=5/2;
2) the phrase 'after Jacky gave 15 dolls to Peter, they have an equal number of dolls' can be written as j-15=p;
3) using the two above it is possible to make up the system of two equations:
4) finally, the have together 10+25=35 doll-s.
