To get the probability of two individual events both occurring,
you have to multiply the probabilities of their individual events occurring. Therefore
in this problem, the probability that a student selected at random will pass
both French 101 and French 102 is 0.683 (.75 x .91). The answer is already
rounded to three decimal places.
Answer:
the number of senors is 150
Step-by-step explanation:
call the number of seniors is a
we have number of juniors is 4/3a
number of sophomores is 3/2*4/3*a=2a
number of freshmen is also =2a
sum of all studens in that school = a+4/3a+4a=950
a=150
X=4 and y=6
For this, you should use simultaneous equations
8,000,000 pennies equals $80,000. 1/.05=20
20 x $80,000=$1,600,000 more that the bank was able to lend
