    To calculate the probability of each event occurring you will need to know there are 7 consonants and 3 vowels. You will use this to find the probability of each set of events occurring and multiply them together.

    a. 1/10 x 1/9 = 1/90 chance

    b. 3/10 x 1/9 = 1/30 chance

    c. 7/10 x 2/9 = 7/45 chance

    d. 3/10 x 7/9 = 7/30 chance
