1. Given that,

   • Number of red balls = 3
   • Number of black balls = 4

   Let’s calculate the probability of black balls,

   • Probability = Favorable outcomes / Total outcomes
   • Favorable outcomes = 3
   • Total outcomes = 3+4 = 7
   • Probability = 3/7

   Let’s calculate the probability of black balls,

   • Favorable outcomes = 4
   • Total outcomes = 7
   • Probability = 4/7

   Hope this helps you.

   Thank you for your question.
