X, is assumed to be a random variable by placing letters of the word “YACHT” in a hat. If these letters are withdrawn then it gets replaced. A value of 1 is given when a vowel is retrieved, and a value of 2 is given when a consonant is retrieved while a value of 3 is given to all other retrieved letters. 1. Write the sample space on which X is defined? 2. Construct a probability distribution of X. read less

Probability Question: X, is assumed to be a random variable by placing letters of the word “YACHT” in a hat. If these letters are withdrawn then it gets replaced. A value of 1 is given when a vowel is retrieved, and a value of 2 is given when a consonant is retrieved while a value of 3 is given to all other retrieved letters. Write down the sample space on which X variable is defined.Can we write the sample space as given below: Since Y-2, A-1, C-2, H-2, T-2 Sample space = {1 and 2}. read less

• V stands for "Vinculum" or "Bar"
• B stands for "Bracket" (order as small,medium,big)
• O stands for "Of"
• D stands for "Divisibility"
• M stands for "multiplication"
• A stands for "Addition"
• S stands for "Subtraction".

 2. Multiplication of signs:

1. Multiplication of two plus gives again a plus.

2. Multipication of two minus gives a plus.
