One box has 80 raffle tickets, of which 35 are red. Another box has 50 raffle tickets, of which 35 are red.
Suppose Mia selects a raffle ticket at random from each box. from which box is she more likely to select a red raffle ticket.
35/50= 0.7(100)= 70% likely

Soledad has a spinner with red, blue, and white section. She spins the spinner 20 times. Based on her results, what is the probability of the spinner landing on each color?
Hint: 5 red, 9 blue, 6 white
Red: 5/20=0.25(100)=25% unlikely
Blue: 9/20=0.45(100)=45% unlikely
White: 6/20=0.3(100)=30% unlikely
each of the 10 letters in the word BIENVENIDO is written on a separate slip of paper and placed in a bag. Each of the 5 letters in the word ADIOS is written on a separate slip of paper and placed in another bag. Khadija plans to select a letter at random from each bag. She thinks she is equally likely to select a D from each bag. Show your work whether you agree or disagree
Is it likely that there are the same number of consonants in the bag?
A,D,E,B,F,C,F,D,E,B,A,B
No, there is less vowels than consonants.
