Answer:

0.7599

Step-by-step explanation:

Probability at least won competition wins

= 1 - he wins no competition

His probability to lose in one competition

= 1 - 0.3 = 0.7

It's probability loosing 4 competition

= 0.7×0.7×0.7×0.7

so required probability

 = 1 - (0.7) {}^{4}  = 1 - 0.2401 = 0.7599
