Answer:
a) 4
b) 12
Step-by-step explanation:
Since, when an orange ball is drawn, three coins are tossed. So, sample points are
OHHH, OHHT, OHTH, OHTT. OTHH, 0THT, OTTH, OTTT
So, clearly, 8 sample points will have an orange ball.
When a blue ball is drawn, two coins are tossed. So, sample points are BHH,BHT,BTH,BTT.
So, clearly, 4 samples points will when a blue ball is drawn.
Total samples points=4+8=12
