help guys... urgently​

Answer 1

Step-by-step explanation:

Total no. of outcomes = 3+5+4 = 12

probability of red ball =$\frac{no. of red balls}{total no. of outcomes}$=$\frac{3}{12}$=$\frac{1}{4}$

probability of black ball = $\frac{no. of blackballs}{/totalno.ofoutcomes}$ = $\frac{5}{12}$

probability of blue ball =$\frac{no.ofblueballs}{totalno.ofoutcomes}$=$\frac{4}{12}$=$\frac{1}{3}$
