Step-by-step explanation:
Answer:
Let the no. of messages Jina send be x.
No. of messages Kevin send=x-5
No. of messages Chang send=3(x-5)
=3x-15
x+(x-5)+(3x-15)=130
x+x-5+3x-15=130
x+x+3x-5-15=130
5x-20=130
5x=130+20
=150
x=150÷5
=30
No. of messages Jina sent=30
No. of messages Kevin sent=30-5
=25
No. of messages Chang sent=3(30)-15
=90-15
=75
Answer:
50%
Step-by-step explanation:
The chances of getting either heads or tails on a coin is 50/50. Convert that to probability and that is 1/2. Convert it to percentage of 100 and it is 50%.
Only time a coin isn't 50/50 is if the coin itself is a weighted coin.
