you mix the letters M A T H M A T I C A l thoroughly without looking you draw one letter find the probabilaty write the probabilityas a

@lilkg77
OpenStudy (sshayer):
count the total number of letters
OpenStudy (jake124):
11
OpenStudy (campbell_st):
just use
P(A) = number of A's/total number of letters
OpenStudy (sshayer):
one by one choose
number of M's

OpenStudy (jake124):
im confused
OpenStudy (jtvatsim):
Are we missing something in the question? It seems like the question got cut off. It says "find the probability" but what are we finding the probability of?
OpenStudy (jake124):
no i wrote the question how it was wrote
OpenStudy (sshayer):
\[P(M)=\frac{ number~ of ~M's }{ total~ number~ of~ letters }\]
OpenStudy (campbell_st):
so you need to find the probability of an A being selected
is that the way the question reads

OpenStudy (jake124):
yes
OpenStudy (sshayer):
similarly for other letters
OpenStudy (jake124):
whats the answer
OpenStudy (sshayer):
you cont number of M's
OpenStudy (jake124):
theres 2 m's

OpenStudy (sshayer):
so probability of drawing M will be=?
OpenStudy (jake124):
2 ?
OpenStudy (sshayer):
formula is above written
OpenStudy (sshayer):
you have to fill the values only.
OpenStudy (jake124):
im sorry im not really good at math can you explain ?

OpenStudy (sshayer):
\[P(M)=\frac{ 2 }{ 11 }\]
OpenStudy (sshayer):
similarly you show me for A
OpenStudy (jake124):
11 ?
OpenStudy (sshayer):
\[P(A)=\frac{ number ~of A's }{ total ~number~of~letters }\]
OpenStudy (sshayer):
How many A's?

OpenStudy (jake124):
there a 3 As
OpenStudy (sshayer):
then write the probability of A
OpenStudy (jake124):
3
OpenStudy (sshayer):
how i have found the probability of M
similarly P(A)=?
OpenStudy (jake124):
so 3 is right

OpenStudy (sshayer):
3 is not probability
it is number of A's
OpenStudy (jake124):
so find the probaility of A
OpenStudy (sshayer):
formula for P(A) is written above.
OpenStudy (jake124):
3/4 ?
OpenStudy (sshayer):
from where you get 4.
