The probability that you'll be a magic elf is or 6.66%.
Step-by-step explanation:
Step 1:
Let A be the event of you choosing an elf.
The probability of an event is given by dividing the number of favorable outcomes by the total number of outcomes.
Here the number of favorable outcomes is 1 and the total number of outcomes is 3 i.e. elf, hobbit or human.
The probability of choosing an elf,
Step 2:
Let B be the event of you choosing magic as your defense.
In this situation, the number of favorable outcomes is 1 and the total number of outcomes is 5 i.e. magic, sword, shield, slingshot, or umbrella.
The probability of choosing magic as your defense,
Step 3:
The probability of both events A and B happening, we multiply the individual probabilities.
Answer:
5
Step-by-step explanation:
Let the number of the kitchen clock sold =a
Let the number of the cuckoo clock sold =b
Let the number of the two-foot high grandfather clocks sold =c
The new saleswoman sold at least two of each of the three models.
Therefore:
In all, she collected $300 from selling these models alone
17a+31b+61c=300
17(2)+31(2)+61(2)=218
300-218=82
Next, we try to express the remainder (82) in terms of 17, 31 and 61
82=17(3)+31
Therefore, she sold:
- 5 kitchen clocks
- 3 cuckoo clocks
- 2 two-foot high grandfather clocks
She sold 5 $17 clocks.
CHECK:
17(5)+31(3)+2(61)=$300
