Answer:
A - 20%
B - 75%
Step-by-step explanation:
To evaluate the possibility of picking one element from an ensemble, without any restrictions, it's simply to count the ratio of possible "good" answers over the total possibilities:
For both scenarios, we'll assume the letters are placed in different pieces of paper in a bag or a bowl from which the selection is done.
A. Probability of choosing a letter from the word SPACE
To simply answer the question as is, the probably is 100% because if you pick a paper from the bag where you placed all the letters of SPACE and you pick one... there's 100% chance you'll get one.
However, I assume the question means "choosing a SPECIFIC letter"... So, there are 5 different letters, the probability to pick any one specific of them is 1/5, so 20%
B. Choosing a consonant from the word MATH.
To pick any specific letter in this case you have a chance of 1/4, so 25%.
However, the question is about consonants... there are 3 of them in that word... so you have 3 chances out of 4 (3/4, 75%) to pick a consonant.
